Bruno Fernandes launched a verbal attack on Ole Gunnar Solskjaer and his Manchester United teammates at half-time against Tottenham last weekend.
The Red Devils were 4-1 down at the break after completely falling apart against Jose Mourinho's visiting side.
It was Fernandes who had scored a penalty to give United the lead after two minutes, but Spurs quickly turned the game on its head with two goals of their own inside 10 minutes.
Things went from bad to worse for the hosts when Anthony Martial was sent off just before the half-hour mark.
With 10 men it was always going to be a struggle and Tottenham scored twice more before the half-time whistle.
While the break gave United players a bit of rest bite from Mourinho's onslaught, it seems they faced a verbal one from Fernandes in the dressing room.
According to the Mirror, the midfielder stormed past match-day officials in the tunnel and started 'lashing out' at teammates.
"We are supposed to be Manchester United!" he reportedly shouted, according to one official.
"You couldn’t help but hear him. He was clearly in a rage after having a face like thunder when he raced down the tunnel.
"He laid into teammates, accusing them of not upholding the proud name of Manchester United. He kept yelling, 'We are supposed to be Manchester United. This shouldn’t be happening'.
As well as laying fellow members of the squad, Fernandes also hit out at Solskjaer's tactics.
"It was clear that the manager also came under fire because he was going on about the wrong tactics.
"There were other raised voices, but his was the one which seemed to carry the main force."
It's hard to blame Fernandes for lashing out at half-time of a match that Man United eventually went on to lose 6-1.
Fans will be very happy to hear their star man isn't going to stand for that kind of performance.
