Romero filled in after David de Gea had picked up an injury during the warm-up in Denmark and the Argentine was superb, pulling off a number of world-class saves.
De Gea will likely miss the FA Cup clash against Shrewsbury on Monday but Romero will be confident of putting in a similarly impressive performance in his absence:
Romero was the only positive for United on what was an awful evening for the club.
It was an encouraging display for the keeper on a personal level but he should not have been given so much to do, with United a shambles at the back.
Louis van Gaal’s side were made to look like amateurs against supposedly inferior opposition and it wouldn’t even be a surprise if Shrewsbury got a positive result out of United on Monday.
