Life after Arsenal – a data driven update on four former Gunners

One of the highlights for me during the recent Besiktas v. Lyon Europa League tie was watching former Gunner Oğuzhan Özyakup. Özyakup never had the chance to break into the first team at Arsenal, but since then has slowly built a very impressive resume for himself at Besiktas in Turkey. It got me thinking about all the promising young players that have come through Arsenal over the past 5-7 years. Each season, Arsenal fans watch them during the preseason tours, and potentially a handful of Carling Cup matches. At the conclusion of each season, a few are released or sold to continue there careers away from Arsenal.

My interest in Özyakup motivated me follow up on a handful of former Gunners. I want to know where they are now, and how they’re playing. As always my approach will be data driven.

And yes, you can consider this article as me outing myself as an Arsenal fan. Watching the French National team during the 2006 World Cup got me into the sport. Zidane, Henry, Ribery, Thuram, Makélélé, Viera, Malouda – amazing side. I remember how different the sport felt compared to the few San Jose Clash games I watched growing up in the 90s. I followed Henry to Arsenal and became a fan during the 2006/2007 season.



Isaac Hayden:

“I like his strengths in the duels… I like his capacity of concentration and I believe as well that technically he is very focused to do well… He is maybe not a creative player but everything he does is intelligent. I like his intelligence and all these qualities together makes me choose him.”

Arsene Wenger

A longtime fixture in the Arsenal youth teams, Isaac Hayden only played a couple Carling Cup matches for Arsenal during the 2013-2014, and 2014-2015 seasons. He then went on loan to the Championship last season with Hull, where he started 9 matches, and came off the bench for another 9. In July of last summer, Arsenal sold Hayden to Newcastle, where he signed a five year deal.

Along with Matthew Palmer, Will Hughes, and Philip Billing, Hayden has established himself as one of the best u-23 central midfielders in the Championship this season. He’s made 27 starts to date for Newcastle, all as a central midfielder (Hayden spent some time as a central defender at Arsenal).

Arsene Wenger was right about his strength in the duel. Hayden has broken up opponents play at an above average rates (adjusted for possession) this season. He is clearly not a pure ball winner, but his tackling, intercepting, and blocking are all about a standard deviation above the mean for a central midfielder. Hayden has also been very strong in the air. He wins headers at very high rates in both the offensive and defensive halves. In addition, his success rates when going for headers are also high.

Hayden’s passing within Newcastle’s system can only be described as ordinary, and conservative. His passing risk (a metric used from my implementation of the expected passing model) is very low, indicating a conservative range of passing. This is confirmed by the rates at which Hayden cycles the ball sideways and sends it backwards. Hayden rarely moves the ball forward, and rarely passes it long. To be fair to him, Newcastle as a team play an above average possession, fairly conservative passing style. Perhaps the team effect is skewing Hayden’s passing profile.

Adjusted for risk (again, using the expected passing model here) Hayden’s passing accuracy is slightly below average. A highly accurate passer when moving the ball laterally, Hayden’s accuracy rates are more troubling when he moves it forward.

Within Newcastle’s passing network, Hayden’s is a fairly influential connective hub. He has played both as the deep man and the middle man in in Newcastle’s 3 man midfield system this season. Hayden’s vertical and laterally touch maps seem to indicate Hayden covers a lot of ground for Newcastle, as well.

Here is Hayden playing a bit deeper than usual in Newcastle’s recent win away to Cardiff (passing network is 11tegen11‘s):

One interesting metric that stands out, especially considering his conservative passing style, is Hayden’s chance creation. His chance creation rate is slightly above the mean for a central midfielder, and his expected assists are a full standard deviation above the mean. Although Hayden plays as a 6, and is a conservative passer of the ball, he is still managing to create chances at surprisingly high rates.

Hayden seems to be adjusting to life after Arsenal very well. I can’t wait to watch how he copes with the Premier League next season.


Thomas Eisfeld:

“He is a Pires type… He appears to be in the box without being noisy and appearing suddenly. When he is there, he finishes well. He has that kind of quality that some midfielders have – not many. They have the timing to get in dangerous situations. When they have those dangerous situations, they are like snakes. They bite you to death because they don’t miss their first touch.”

Arsene Wenger

A year after Arsenal signed Serge Gnabry out of the Stuttgart youth system, Arsenal went back to Germany to sign another promising young attacker – Thomas Eisfeld. Eisfeld came up through the Dortmund youth system before he was allowed to leave for Arsenal in 2012. Like Hayden, Eisfeld only managed a couple appearances in the Carling Cup with the Arsenal first team over the 2012-2013, and 2013-2014 seasons.

In the summer of 2014, Arsenal sold Eisfeld to Fulham. After a successful loan to VFL Bochum, during the 2015-2016 season, Fulham sold Eisfeld to Bochum permanently last summer.

Eisfeld started the 2016-2017 season strong for Bochum, prior to an knee injury that kept him sidelined until April. Even still, Eisfeld’s performances when he has been healthy as a number 10 for Bochum this season are perhaps second only to Greuther Fürth’s Robert Zulj.

Eisfeld’s strength is in his creativity. He creates chances at a very high rate, and expected assists numbers are above average for a number 10, as well. His actual assist total, 2 in around 1100 minutes on the pitch, is lagging far behind his expected assists. In addition to creating chances, Eisfeld has shown indications that Arsene Wenger’s assessment of his play in the box is correct. His expected goal numbers are again, above average for  a number 10, and again, are out pacing his actual goal scoring rate.

Here is Eisfeld playing high up the pitch for Bochum in a recent match (passing network is 11tegen11‘s):


For all Eisfeld’s play making, he’s not a influential connector in Bochum’s passing network. Positionally he has played as the number 10 in mostly 3 man midfields for Bochum, and stays fairly high up the pitch. His passing accuracy adjusted for risk is surprisingly average. Like Hayden, albeit from a very different position on the field, Eisfeld is a conservative passer. Eisfeld has a tendency to play the ball backwards, lay it off, and rarely moves it forward. This is not all that surprising given the position he’s playing, and the fact that Bochum like to play with the ball. Eisfeld also wins fouls at a standard deviation above the mean for a number 10.

Eisfeld’s career seems to be back on the upwards trajectory after some stagnant seasons at Arsenal and Fulham. Bochum look set for another season in the Bundesliga 2., so expect Eisfeld to be a major player in that league barring another injury.


Kristoffer Olsson:

The story goes that Liam Brady persuaded Arsene Wenger to sign Kristoffer Olsson from IFK Norrkoping in Sweden in 2011. Over a few seasons in the Arsenal youth system, Olsson only ever featured for Arsenal during one Carling Cup match in the 2013-2014 season. Olsson spent the 2014-2015 season on loan at FC Midtjylland in Denmark before permanently moving there in the summer of 2015.

Olsson established himself as one of the best young midfielders in Denmark along with FC Nordsjaelland’s Stanislav Lobotka, and Brondby’s ball winner Christian Nørgaard. At Midtjylland, Olsson played high up the pitch in 3 man midfields. For how high up the field Olsson played, he intercepted the ball at above average rates, and tackled at average rates for central midfielders. Olsson doesn’t seem to be a defensive liability in the position he plays. Olsson also covered ground at very high rates, moving laterally and vertically.

Olsson’s play is highlighted by his passing accuracy. Adjusted for passing risk, Olsson’s passing accuracy is almost a standard deviation above the mean for central midfielders. In particular, his passing accuracy moving the ball forward in the middle and final thirds is very high. The profile of his passing is riskier than Eisfeld and Hayden, as well. Olsson rarely moved the ball laterally as he either pushed forward, or laid it off. However, Olsson keeps his passing short, and very rarely passed the ball long. In general, Midtjylland played the ball long only slightly below average while Olsson was there.

Although Olsson played at a similar height on the pitch for Midtjylland as Eisfeld does at Bochum, he isn’t as much of a playmaker. His expected assist and expected goal numbers are above average for central midfielders, but not like Eisfeld’s. An interesting outlier in Olsson’s metrics is his complete lack of winning balls aerially. His numbers are so low there perhaps I need to do some data quality checks…

In January, Olsson transferred to AIK in Sweden. It’s still too early there (5 starts) to properly evaluate his performance there.


Oğuzhan Özyakup:

“I’m happy that he came here… He was educated by us and we saw that he had top quality and technically he is very good. Physically he can run all day, he has very good stamina and a good final pass. I always thought he could make a career but at our club he had big competition in front of him and that is why we let him go. It is good to see he has made it to the top level and is now an important player in Turkey.”

Arsene Wenger

Oğuzhan Özyakup is perhaps the most successful former Arsenal youth to establish himself outside of London in recent history.  In the summer of 2012, Özyakup moved from Arsenal to Besiktas, and over the course of the past five seasons, has slowly established himself on the European and International stages. Özyakup has been capped 25 times in a talented Turkish midfield, and is a regular starter for one of the most progressive attacking sides in Europe. Besiktas regularly play with over 60 percent of the ball, and Özyakup sits at the heart of their possession as an deep lying attacking hub. Last season, Özyakup and Besiktas won the Turkish Super League – the first Besiktas title since the 2008-2009 season.

While Özyakup has started some matches as a number 10 for Besiktas, his regular position is next to Atiba Hutchinson as one of the deeper lying central midfielders in their 3 man midfield. He has a large influence over their possession as his connectivity within their passing network is strong. Özyakup is a brilliant technical player who’s passing accuracy adjusted for risk is very strong. It’s about a standard deviation above the central midfield mean, and about a standard deviation below elite levels (elite being Santi Cazorla,Toni Kroos, and Andres Iniesta). His accuracy in the middle third moving the ball laterally and forward, and his forward passing in the final third are highlights. Özyakup’s passing risk is average. He moves the ball forward, laterally, and backward at average rates.

Özyakup also rarely gives the ball away due to bad touches or being tackled by opposition, characteristics that are important to Besiktas’ heavy possession style of play.

Here is Özyakup playing next to Hutchinson in a recent win over Caykur Rizespor (passing network is 11tegen11‘s):


In addition to Özyakup’s ability in the build up, his data are strong as a play maker as well. Özyakup plays teammates through very often for a central midfielder, and his expected assist and expected goal numbers are also well above average.

Özyakup’s one weakness may be his defensive contribution. Adjusted for possession he doesn’t break up the opposition’s play at high rates. His tackling rates in particular are below average. Additionally, like Olsson, Özyakup isn’t a threat aerially.

Özyakup’s name is often in the transfer news these days. I am hoping he makes the jump to Spain, Germany, or England this summer.

It seems life after Arsenal for Hayden, Eisfeld, Olsson, and Özyakup has been quite good. All four seem to be on the upwards trajectory in Europe. I look forward to following their careers over the next few seasons.
