On the plus side it indicates he's a selfless and intelligent footballer. Nothing more stupid than people saying "oh he should never have a got a second yellow for that one". Well he knew he was on a booking so what did he expect?
I'm happy to ignore post-booking, we've seen enough of him to know that he should make it in the PL, hopefully with us.
He absolutely will, I'm sure of it. He looks very powerful these days and this loan will do him the power of good. I think Mourinho has him pencilled in as rotation player next season.
