You can't reason with some of these guys once they dislike a player. There's alot of you here. If a player does well, you keep quiet, but when he does bad, you are the first people to criticize him. It mostly happens with Henry, Toure, Marquez, Keita, Zlatan, and up until recently, it happened with Maxwell.
I didn't get so see the Espanyol game live but downloaded it and watched again. You guys have exaggerated the performance of Yaya. Maybe it was because we tied and your emotions were up, but he had an ok game. Certainly not the worst, of course not the best. As for his effort, there were times when he didn't put a lot of effort, and there were times where he went all out. I don't know the reason why he did that, but it was just one game.
Messi hasn't scored in three or four games, should we bench him? No. Yaya doesn't have a good game and everybody wants to bench him. Also, you should give Yaya some lenience by the fact he hasn't been playing consistently. That's of course of you don't like him.
Whatever, I know this is going to make me sound like I hate Busquets, but I don't. I just think that they have different styles and their styles should be used for different types of games.
