Manchester City boss Pep Guardiola was full of praise for Phil Foden after victory over Manchester United.
Foden scored twice in Sunday's 3-1 win.
Guardiola said: "It is the amount of games he is playing. He was always a talented player but now he is more mature and understands more the game, especially defensively. He can play middle, right, make moments and cut inside, play in the left, scoring from the left. What can I say?
"He is the best player in the Premier League right now for the amount of things he does. Unbelievable.
"When he scores two goals it gives me more pleasure than the other stuff (defensive work). We don't negotiate over that, the guy who doesn't do that doesn't stay in the team.
"He loves football, he lives for football. He is a joy and his work ethic is unbelievable."
