The Stockport-born City fan proved the matchwinner in Wednesday night's hard-fought 1-0 triumph over Brentford, converting Kevin De Bruyne's cross with an excellent first-time finish to clinch a precious three points and extend the Champions' lead atop the Premier League to eight points.
Guardiola was full of praise for the 21-year-old, who shone once again, showcasing his versatility, technique and game management.
"Phil has always been outstanding since he came up with us to start to train and play," the City boss said.
"He is a guy who can play in different positions and at an exceptional level.
"He is always a good player and we had no doubts about that.
"He does not need to prove anything to me. He needs to enjoy football like he used to as a little boy."
