Jose Mourinho involved in epic prank

New Manchester United manager Jose Mourinho has proven he still has a mischievous streak, after helping YouTube channel Top Eleven pull off a hilarious prank.

During a live broadcast with their host Joe Thomlinson and experts Patrick van Straaten and David Jackson, the channel enlisted the Portuguese manager to provide a cleaning lady standing nearby with some facts and statistics about Euro 2016 via a hidden earpiece.

The director was in on the joke, but watch as the hosts and guests are left gobsmacked by the lady’s spot-on football knowledge, as she sums up Austria’s progress in qualifying and one of their star players, David Alaba.

‘They’ve got Alaba who’s fantastic, he’s got 42 caps and he’s what 23 years of age..he’s won the Bundesliga five times, the Champions League, World Club Cup,’ she proclaims.

All the info was coming from Mourinho, of course, but the lads were none the wiser.

The lady continues to blow them away with her incredible knowledge until Mourinho steps in to give up the game – just as he becomes part of the conversation.
