Dominc Calvert-Lewin found him inside the box and the striker steered the ball under Ederson's legs and into the back of the net.

He is only the second player to reach the 200-goal milestone in the Premier League era after Alan Shearer, who scored 260 goals for Blackburn Rovers and Newcastle United.
Rooney scoring his 200th PL goal vs city... so romantic!
