This is one duel you won't want to miss...

The gauntlet has been thrown down.

Bernardo's touch and technique is not only one of the best at City, it's among the best in the world.

So when he is challenged by Jack Grealish for a game of head tennis, can he show the England star who is boss?

Or will Jack's silky skills see off the Portuguese crowd idol?

Watched by KDB, Kyle Walker, Rodrigo, John Stones and other City stars, it is a tense battle that will go right down to the wire - including a VAR decision for handball.

Who wins? Watch the video above to find out!
