He doesn't suck, but tbh he's not good either. Especially not for you guys. We bought Caceres cause' he's supposed to fit in with our defensive style/tactics - we pressure very high and leave our 2 CBs exposed and maybe help out a little with our DM and LB (Abidal). Hell, even Alves plays more of a winger than RB. It's high risk but it paid of this season.
Anyway, back to Caceres. He is atm not wirth the €15 mills and he's not even near good enough to play in Juventus. He just might turn out to be a great player in 1-2 years, but not yet.
