Well, that's where we agree to disagree. Although its not my money, I would rather see it spent on a young player to groom as a future superstar, than one who has already peaked, and has started to decline, even if its for the sake of a scudetto.
I'm sure Wenger is laughing all the way to the bank with the money that he pilfered for Vieira. "Oh you mean that Cesc Fabregas has to play every match now?? Oh, what a shame."
