Walker reminds me of a really top tier American Football cornerback.
He just covers about 1/3rd of the pitch and you know that if someone tries to breakaway in that third, or a ball is played through, he is going to get the and win it. Playing the ball to someone 1v1 with him is futile, and if we've not already seen it, then we soon will see people just not bother playing the ball out that side. People like Zaha, Adama Traore etc will just stay as far away from him as possible.
I've said it before but I think he's the best defender in the world in open play by a mile.
Nice to see him get some recognition.
