I have no problem with his transfer policy, I have no need to have an expensive player, a free transfer that can play football can be as good as a 30million pound player.
The thing is, if you buy any players and they time and time again prove they aren't good enough, paying them is a waste. Diaby was woeful, has he started every game since the Pompie game, yes he finished two chances well, he was fairly quiet in that game apart from the goals except when trying to run past Mullins, who I with two bad knee's and overweight could have done. He's been terrible in every game since, considering Eboue creates more chances, is far better defensively, is much faster, why we keep dropping Sagna to play Eboue rather than drop Diaby I don't know. But we could just play a 4-4-2 with another striker instead of him, Vela, Eduardo, Bendtner, Arshavin and in the future Nasri can play withdrawn striker also. Theres maybe 10 players in the squad who are simply a lot better than Diaby already, why we start Diaby I do not know.
Do I find it surprising that we scored within 60 seconds of him going off, no, the movement of the entire team was FAR better when we switched to 4-4-2 with players who know where to run.
I'd happily get a couple cheap players and try them even if they turn out bad, than play Diaby who we KNOW isn't good enough.
I don't doubt that Wenger would spend if he thought it was necessary, the problem, as it has been for 3 years, is that Wenger thinks Diaby, Song and Denilson are good enough.
I can't see any reason whatsoever to buying an Aguero or Villa, even if they were only 15mil, because in a 4-3-3 with one real striker being played at a time, we have more than enough quality. WE have the players, we have a great squad with tonnes of depth in all attacking area's, we could do with a centre back, even though we have 5 centre backs. THe problem is faith in the wrong players in the squad who have clearly underperformed game after game.
