The optimist in me wants to cite the fact Arsene has been a long standing admirer of the player and he's put up some impressive numbers at Lyon. He could, hopefully do great things given good service. He's 26 and could have the best years of his career at Arsenal.
On the other hand, we allegedly could have bought the same players last year for less money or the year before for even less money. It does feel a little anticlimactic considering his arrival could just be a prelude to Alexis leaving this summer and not a chance to add actual depth to the squad. It feels a tiny bit like Arsene was scrambling for a striker (again) this summer and just went back to his list from last year and the year before.
