You have to understand that at first, Mascherano was STEPPING IN as a cb. He was playing there once in a while to help us out, and that made him very valuable- it still does. However, Masch is not a cb and it is clearly evident now that he's been pretty much played as one for us. He makes mistakes (sure, so does everyone) but he makes a lot of fundamental mistakes. Like going for a header but bailing on it last second or misjudging it- everyone knows most midfielders do that all the time, mostly because they just want to contest it so the opponent doesn't clearly win it, in the end neither winning it. Sometimes this is his mentality, except he forgets that he has no one behind him as a cb.
It's small things like that, that has cost us games and almost cost us other goals. Don't get me wrong, imo he's done far better than we could expect for a DM being forced to play as a CB, but the fact stands- we should and deserve better in defense. It's not his fault, I'd be happy buying a WC CB and keeping him as our 3rd option....but I don't think he'd stay on the bench more than not.
I agree with some posters, height isn't everything when it comes to aerial battles. Puyol is better than Pique, and Pique is probably 3-4 inches taller. Busquets is absolutely USELESS in the air.
For CBs, you need a beast that gives his all and wins battles (formerly Puyol) and someone great in the air.
- We currently have neither.
