Everything was going as planned for Jose Mourinho...until Paul Pogba came in for the Red Devils.

Manchester United has been shocked by Sevilla in the UEFA Champions League's Round of 16, and they seem to know the reason beyond Mourinho's tactics: Paul Pogba.

The French midfielder displayed his very poor form during his substitute appearance against Los Hispalenses, and his substitution couldn't have come in a worse moment for the Red Devils, as Sevilla took the lead when he was brought in to change the game. He did, but not for the team that's paying him to do so.

His antics on the pitch caught the attention of those watching, whether they were fans or experts. Have a look at their comments and massive trolling.
