MANCHESTER UNITED chief Darren Fletcher faces an FA charge after claims of a fiery tunnel bust-up with officials.
United were furious as defender Matthijs de Ligt was ordered off the Old Trafford pitch in first-half stoppage time with blood on his head and face.
This was the result of an earlier injury which medics had twice tried to patch up.
As soon as De Ligt left the field, Brentford scored from a corner, sparking outrage with manager Erik ten Hag and No 2 Ruud van Nistelrooy booked for protesting.
Van Nistelrooy continued his protests down the tunnel, while former United midfielder and technical director Fletcher waited inside where he allegedly verbally confronted ref Sam Barrott and fourth official Gavin Ward.
The FA will now await the referee’s report before deciding whether to take further action.
United came back to win the game with Alejandro Garnacho scoring just after the break and Rasmus Hojlund getting a 62nd-minute winner.
Yet Ten Hag was still fuming with the ref’s decision after the game.
He raged: “It was dry blood so he was already treated for the injury.
“I didn’t understand why he was sent off.
“I went over to Matthijs and he said, ‘It is dry blood and I have to come off I don’t know why’.
“It was a huge moment because Brentford is very good at corners and you are missing one of your best headers.”
