I think he was benched for being at fault for Derby's goal, then was annoyed at not getting on sooner against Bristol and finally lost his rag at being told mucking about with the Bristol fans was out of order.
He sulked for 2 months after being left out of the squad for the African Cup of Nations. His form at that time was awful.
He needs to grow up and get his head down. We have a much better squad than last year and he will be left out if he doesn't man up and deal with it.
Karanka just has to see how he responds. He's shown with Muzzy that having a new contract means nothing. That is the club protecting an investment. Karanka decides who plays and who doesn't.
