Jeff Reine-Adelaide’s market value has seen one of the sharpest increases of players in the big-five European leagues, according to the Football Observatory.

The CIES Football Observatory released a post on Monday of the top transfer value increases for players in the big-five leagues over the last three months. They made two ‘top 20’ lists, one in terms of absolute increase (the greatest increase in €m) and one in terms of relative increase (the greatest increase in %).

Former Gunner Jeff Reine-Adelaide made the relative increase list, coming in at 20th with an increase of 137%. According to the Football Observatory, his market value has gone from €3.5m in September to €8.3m in December.

The main driving force behind the increase is probably the fact that Reine-Adelaide is finally playing regular senior football. He only made eight senior appearances in a few years at Arsenal, and injuries kept him to just seven starts in his loan spell with Angers last year.

Since joining the Ligue 1 club permanently, Reine-Adelaide has 13 starts to his name, including a run of the nine most recent league matches. As a 20-year-old playing regularly in a top league, it’s no surprise his value is starting to go up.

Should Arsenal have held onto him?

It’s difficult to judge just how good Reine-Adelaide can be at this stage. Angers clearly believe in him, but the statistics show a mixed start to life at senior level.

Despite his 15 Ligue 1 appearances, the Frenchman is yet to score for his new club, and he has just one assist. For a largely attacking player, those numbers could certainly be better.

At the same time, Reine-Adelaide is undoubtedly excelling in one area: Dribbling. He consistently features in lists of the most effective young dribblers at this level.

In addition, the former Gunner is creating a lot of chances. He’s made 18 this season, and the only Angers teammate to make more is Flavien Tait (29). The problem seems to be just that those teammates aren’t converting their opportunities. If they start doing so, Reine-Adelaide’s assist numbers should start to rise.

Nonetheless, Arsenal couldn’t have offered the player these same chances to work on his game. The Gunners need results now, and Reine-Adelaide remains a work in progress. Hopefully, he reaches his potential, but Arsenal shouldn’t feel too bad about selling him on.
