It's not just on the pitch where Manchester City are battling it out to be the best.
On a high after the Blues beat title rivals Chelsea on Saturday, Jack Grealish challenged Bernardo Silva to a game of head tennis.
It was a brave move as the Portugal midfielder's touch and technique is regarded as among the best in the world.
But Grealish has also wowed fans with his nifty footwork.
And the pair showed off their amazing skills as they went head-to-head at city's training ground on Tuesday.
