Phil Foden says he feels "100% fit" after "one of the worst parts of my career" as his double sent Manchester City past Championship side Bristol City into the FA Cup quarter-finals.

England attacking midfielder Foden lost his place in his side's starting line-up after some disappointing performances following the World Cup.

But he has now scored three goals in four days, having netted against Bournemouth on Saturday, and Manchester City manager Pep Guardiola said Foden was "back for the best bit of the season".

The 22-year-old slammed in an early opener at the back post from Riyad Mahrez's ball across the six-yard box.

He netted his second from Julian Alvarez's pass, with a first-time effort deflecting past Max O'Leary.

Kevin de Bruyne added a wonderful third from 25 yards into the bottom corner late on for the visitors.

"I feel much better with my feet," said Foden. "I feel 100% fit now and comfortable. It has been one of the worst parts of my career but everyone goes through them and it is how you react.

"[The issue was] discomfort in my feet and not playing as much. I love to play football and when I don't I am a bit frustrated."

Guardiola said: "His career was always up, up, up. This season he struggled a bit and was a bit down. But now he's back for the best bit of the season."
