The Special One and his player exchanged harsh words during Wednesday's training session, causing controversy among fans.

The less-than-amicable exchange between Jose Mourinho and Paul Pogba stole some headlines today, but the question was left floating in the air. What did Mourinho tell Pogba that caused Pogba to give him such an enraged look?

According to a report by the Daily Mail, the argument between the French superstar and the Portuguese coach was caused by Pogba's social media activity during the game between Manchester and Derby County, where the Frenchman posted a video of himself, Andreas Pereira and a Luke Shaw living it up in one of Old Trafford's boxes moments after the game concluded.

Furthermore, Mourinho complained about Pogba's lack of respect for the team's dress code, as he entered the locker room wearing a bright white tracksuit and gold-rimmed glases.

In the footage shared by Sky Sports, Mourinho called media relations manager John Allen to clarify Pogba's activity on social media. A puzzled Pogba stared at Mourinho before stating "It's my problem. Why can't I do nothing? I come here and do nothing. This is my problem," Pogba allegedly replied.

Have a look at the detailed description of the incident published by Sky Sports.

The team's training session carried on, but Pogba seemed to be quite angry throughout. Jose Mourinho kept on watching his players work out, as Manchester United prepares for one more EPL game, this time, against Manuel Pellegrini's West Ham United.
