KEVIN DE BRUYNE appeared to lash out at team-mate Toby Alderweireld during a fiesty encounter with manager Roberto Martinez.
The Belgium talisman was not happy with the way his team were playing against Canada, who dominated the first half of their match on Wednesday.
The Red Devils managed to take the lead against the run of play and De Bruyne decided the vent his frustrations as his team-mates celebrated Michy Batshuayi's goal.
He ran over to the touchline to speak with Martinez, who held the midfielder's arm as he attempted to calm him down.
Former Tottenham star Alderweirreld then ran over to intervene but De Bruyne forcefully waved him away in a clear sign of frustration.
De Bruyne played down the disagreement after the match as he explained he only had an issue with the team's tactics.

He told : “It was emotion. We’re men, not choirboys. It was about details. Everything’s been talked about.
"It was about football matters. That was our discussion. That we were looking for the long ball too much while there was room.
"It was not good. We didn't build up well while there was a lot of space.
“It wasn't good enough, but we know what to change. The precision was lacking, also with me. There was fighting spirit, that is a minimum requirement.”
