You seem to be a bit touchy about this...
I've not said anything about Walker's play being 'revolutionary'... just not what people seem to expect of a traditional full back like, say, Zaba was.
It could be said that Walker played a more traditional role at Spurs, but it can't be denied that his role has adapted significantly under Pep Guardiola, and that he is now a more complete player, who is comfortable enough when taking up a midfield position.
The fact is that Kyle Walker is a key member of the team who can adapt quickly to a number of roles to fit Pep's tactics.
He's a street better than Cancelo in my opinion, and is up there with the likes of Fernandinho in terms of players that we will struggle to replace when they eventually leave City.
I can tell from your argumentative attitude in response to my post that you'll continue to disagree with me on this. That's entirely your perogative, but you have to remember that this forum involves differing opinions and the need to accept that people won't always agree.
Just because you've named yourself after Phil Foden on here doesn't make you an expert on the game. ;-)
