Norwich and Palace are just two that spring to mind where he was awful.He is good enough to start all Cup games ( Except knock out CL )
He can also be good enough to start against most of PL teams ( Apart from top 6 )
I would give him one last dance this season with Laporte, and I think he can regain his place in the team.
On top of that, he's never fit. He's good for nothing, sell and get some cash. How can he seriously expect to be at a team that challenges given his form over the past 18 months. Examples need to be made of these sort of players
