Manchester United midfielder Scott McTominay admits they showed Barcelona too much respect in the opening exchanges of their 1-0 defeat.

A Luke Shaw own goal separates the teams going to Barcelona for the second-leg of the Champions League quarterfinal.

McTominay said, "In the first 10 minutes we showed them far too much respect but after that we adapted really well and looked the better side. It was an entertaining night to watch on the TV.

"Barcelona are top class, it's difficult to get the ball. It's not as easy as going out to press like mayhem.

"We have to do more in front of goal, score more goals. It's a big second leg to go. It's only half time. We are Manchester United and you can never write us off."
