Manchester United fans criticised referee Maurizio Mariani for his performance in the Europa League play off clash with Barcelona on Thursday night.
Erik ten Hag's side drew 2-2 with the Catalan giants in the first leg, leaving the Reds in a decent position ahead of the return at Old Trafford next Thursday. The Nou Camp game was a classic which saw Barcelona go in front through Marcus Alonso before the in-form Marcus Rashford made it 1-1 just two minutes later with a clinical finish past Marc-Andre ter Stegen. United then went ahead thanks to an own goal from Jules Kounde before the hosts levelled 15 minutes from time through Raphina.
There was plenty to admire about ten Hag's side's performance but the United fans had a major gripe with the officials, believing Barcelona should have had a man sent off midway through the second half when Kounde felled Rashford. The in form United man had latched on to a Bruno Fernandes through ball and was seemingly brought down on the edge of the penalty area.
