Mauricio Pochettino has nailed 'The Dele Alli Challenge'.
Forget Drake's 'Kiki Challenge', there's a new viral move sweeping the internet.
It's not a dance but a complicated hand/arm gesture. Well, complicated for some.

It became a thing after Alli's goal against Newcastle United on the opening weekend of the Premier League.
He headed in a goal for Spurs then wheeled away in celebration, producing a sign with his hand. Everyone has attempted it since.
We mean everyone; from football fans to fellow professionals including the Manchester United lot.
Not to mention Alli's boss Pochettino who has tired his hand at it and nailed 'The Alli Challenge'.
The Argentine gaffer was quizzed about Alli's celebration in his pre-match press conference though refused to demonstrate it.
"I tried one time and it was perfect. He (Dele) said 'fantastic, that's why you're the boss'. But now we're in a very serious press conference and conversation," he said.
"Maybe I show you after."
However, he eventually revealed his handy work following the presser when he was with the clubs media team.
Meanwhile, Spurs resume their league campaign this Saturday when they entertain Fulham.
Will Alli get on the score-sheet and produce his now infamous celebration?
