Surprised by the comments here. I was supporting him back in October when others were doubting him, but tonight wasn't his night in my view. Busquets got the better of him in quite a few aerial duels and his positioning in front of the defence was a little all over the place. I'm sure some of that was tactical though - he had a very tough job in there and wasn't poor by any means. But he wasn't great or even good either.
He'll learn a lot from that game though, as they all will.
My initial reaction was similar.
I think him, Gomez and VvD, and to a lesser extent Alisson, are in the same boat. They did OK and didn't really do a lot wrong. However, none of them had great games either. I'm taking 8, 9, 10 out of 10 performances. They were all 6 or 7 out of 10. Good but not great.
It's not a criticism but against Messi and their attack we probably needed everyone to be 8 out of 10 or above. Definitely in a defensive sense we needed it. We were a shade below that and Barcelona exploited it ruthlessly.
