Manchester City playmaker Jack Grealish was elated after scoring his first FA Cup goal.

The England international bagged himself a goal in the 2-0 win over Peterborough United on Tuesday, which booked City's place in the quarter-finals.

"It's about time isn't it?!" Grealish told the club's website. "I'm over the moon to score. I've got to go in there now and thank Phil for the assist.

"I am over the moon to score but it's not about me. Obviously, I want to score and I want to assist, but the main thing to do tonight was go through to the next round and we did that.

"It was a difficult game. We knew it was going to be that. We finally broke them in the second half and our quality shone through."
