Erik Ten Hag was left furious that Barcelona were not reduced to 10 men after an epic encounter at the Nou Camp.
Manchester United were leading 2-1 in Catalunya when Marcus Rashford went down under a challenge from Jules Kounde in the 67th minute, as he surged towards the Barcelona goal. Rashford and United appealed for a penalty, but Italian referee Maurizio Mariani refused to be swayed and booked Red Devils' boss Ten Hag for his furious protests on the touchline.
Barca then salvaged a draw with a 76th-minute equaliser from ex-Leeds winger Raphinha, with Ten Hag and Rashford both fuming over the penalty controversy.
