Arsenal – Laurent Koscielny
Christ, how do we measure this? Mesut Ozil is perhaps the player who best sums up Arsenal’s decade and Pierre-Emerick Aubameyang has certainly offered value for money despite being a record signing. But can any signing made in the last ten years claim to have given more to the Gunners than Koscielny? The France defender blotted his copybook with the manner of his exit, but at age 33 with persistent injury problems, Koscielny was still too heavily relied upon by Unai Emery after being one of Arsene Wenger’s most trusted players. The former Lorient centre-back averaged 28 Premier League appearances over nine seasons, scoring pivotal goals in FA Cup finals and final-day clashes. Not bad for £8.5million.
