Walker's game is all about his pace and looking at him recently he has lost half a yard hopefully this is just fatigue , Danilo is the better option on current form but Walker will eventually regain his place he is still one of the best right backs in europe when fully fit , and when the chips are down and we are scrapping for a result then Walker gets my vote over Danilo because Walker is a player who gets stuck in regardless and is rarely second best to any winger.
Good post mate, but I think you're being unfair on him in the bit I bolded. He actually has very good positioning and reading of the game for a right back. And in general he's got great technical ability. You don't play for City just because you're a good athlete.
