WEll considering we're looking to buy Arshavin for, the right side, and Theo's supposed to be a month away from return and Fabregas and Rosicky two months away. Thats theo, Rosicky, Nasri all for two places anyway, with Eboue, Wilshire, ramsey(ish), Vela, Eduardo all as backup wingers. Signing Arshavin is lunacy, pure insanity. 15mil for a player who can play all the positions we have covered. I wouldn't mind if we were buying him as a striker, but then again, we've got what Ade who he won't drop, RVP who is the best player in the squad by a mile right now, Vela, Bendtner, Eduardo, Theo. Unless he will finally drop Ade and looks to sell him in the summer then I see no way he will fit into the current squad, and he's completely unproven in a top league.
Not to mention the way Wenger bloods foreign players, in his slow ass no matter how good they are they won't start more than 3 game in the first 6 months, by which time everyone injured will have long since been back, I just can't see it.
