Not sure if it's been mentioned yet. But there was a moment when Walker kept the ball in (play) 'in extremis' with a sort of back heel that was followed by one of those 50-pass moves resulting in that chance that Mahrez crossed towards Foden. Credit to the Villa defender who got back and conceded a corner. If he hadn't, Foden would have had a tap-in. And we would be talking about one of the great team goals of all time. As it was, the TV team didn't bother to comment on it. And it will be forgotten forever.
