Hmm.. I thought he did okay. He did get out worked a few times but managed to make up for it with some key tackles and clearances of his own. I'm not a Pique apologist like I once was, but I'm also not going to set impossible expectations for him either. Every defender makes mistakes, it's managing those mistakes and bouncing back and keeping everyone on their toes, which he does for the most part these days. He's alright.
But is he Barca material alright? lets face facts, Pique is nowhere near as good as he was years ago. Also what do you think is the difference between Barca few years ago ( dominant force ), and Barca now ( 7-0 against Bayern )? I think that is quite a good question..
Goalkeeper? Valdes is still Valdes, no big difference.
Attack? Messi is even better than he was then, Neymar is very good and a big talent, sanchez this season has been smoking, good subs too with pedro and tello and such..
Midfield? No big difference here, Busquets is better, Iniesta still kicks ass, Xavi might not be the player he was but he is still controling the game and having nice matches from time to time, addition of Cesc...
Defence?... well now we are getting somewhere.. Honestly, would our defence with prime Puyol, Abidal, better Pique and better Alves get buttr*ped by bayern with 7 goals in 2 matches... never.
