Man United boss Erik ten Hag says his team were “angry” when Brentford scored from a corner after Matthijs de Ligt was ordered to leave the pitch with a bloody head.
The Dutch defender collided with Kevin Schade’s knee after going for the ball with his head, causing him to bleed profusely. He returned to the pitch following concussion protocols but blood continued to pour from his head, forcing him off the pitch for more treatment.
De Ligt had to come off for a third time in injury time as more blood seeped from the wound, but while he was out of the action Ethan Pinnock scored from a corner to put the Bees ahead.
Ten Hag was booked for protesting at the removal of one of his key men, but referee Samuel Barrot was bound by the rules which state that a player has to leave the pitch if they are bleeding.
