Yeah. Also Sergio stops a lot of counters by being in the right place and making an interception. It's when the ball passes him (inevitable sometimes) that the back four doesn't do it's job and we concede. It's not Sergio's fault at all.
Without him our tiki taka combinations in the middle wouldn't have happened. He either starts them or is involved. I doubt we'd have won 2011 CL and league in that style without him.
Surprising, I thought he would have done a lot better.
Also I agree zlatan should have been in the top five in the balon dor at some point. I thought around 2008 and 2009 he was sensational.
