As I said after the Arsenal match, he is too slow on the ball and he is nonchalant. The effects have been seen in the last three matches: He plays his team mates into troubles and this invites our opponents into the game and they put so much pressure on us that we concede.
And he is hardly a proven PL defender. He had a great season with us last year, but he was not good enough for Bornemouth. I think the key to our survival lies in our two CBs and our defensive midfielder.
Will of course give him some more time, but I fear the times when he will face the good strikers.
