#2 Mangala fails to deliver on the big stage
Having been once considered as one of the brightest prospects in world football, Mangala has seen his stock fall rather quickly. After his big money move to Manchester City, Mangala failed to rise up to the challenge and was ultimately shipped to Valencia on loan.
Though he has been a regular for Valencia this season, his errors have often proved costly for the team, which turned out to be the case against Barcelona, again.
He started the game in the best possible fashion when he nodded home from a corner to give his side a surprise lead. His luck soon ran out as he received a straight red card for his silly tackle in the penalty box on Luis Suarez. If he doesn't curtail his brash challenges, Valencia won't take the decision of signing him on a permanent basis.
