Tottenham star Dele Alli turning 22 on Wednesday and celebrated by having a respectable crack at the notoriously difficult 'Backpack Kid' dance in the changing room.
The England international was put on the spot by his team-mate Serge Aurier, but he thrived under the pressure by performing a version of the dance craze that took the world by storm last year.
It involves completing a series of coordinated arm swings and then rapidly increasing the speed to give the illusion that the video has been sped up. Alli was able to keep it up for several seconds before losing his rhythm.
