I'm not against spending a decent amount of money on a fullback, provided he's actually good. For someone like Cissokho, we would be spending Thuram-like money for someone who isn't anywhere near his level of defending. Same with Coentrao, I'm not convinced he's worth that much money. The fact of the matter is, there aren't that many good fullbacks available these days and we have limited capital to spend. Blowing 30M on a player like Coentrao when we could buy a player like Aguero for 40 just doesn't seem like good business to me. We need quality in all areas of the pitch, but with regards to individual players, those who can score and create a lot of goals are always more valuable to a team than a fullback, unless the fullback is an out-of-this-world player.
