He has saved us a lot of times with his power and pace, especially when teams are counter-attacking us, but I thought he was poor today, he needs a rest, hopefully Danilo can step up, I'm sure Danilo has a lot more to offer than what we've seen so far.
Walker does have some odd habits, imo no good ones that he needs ditch. That weird hopping with leg in the air thing he did went attempting to and failing to block the shot for Palace's first goal what the hell was that? ..... and there a quite a few times when the balls laid onto him when he could whip a cross in first time, instead he uses the sole of his boot to either trap the ball or roll it out a few yards out in front of him (thus giving the opposition opportunity to close him down) before attempting to cross the ball.
Pep's right, we can;t give away penalties like that, think he just had a rush of blood to the head .... Like I said, he needs a rest ...
