Manchester United midfielder Scott McTominay feels it would be wrong for people to write them off in the Champions League despite falling 1-0 at home to Barcelona.
A first-half own goal from Luke Shaw was all that separated the two sides on the night at Old Trafford as Barcelona took control of the quarter-final tie.
McTominay started the match and was one of the standout performers for United in what proved to be a fiercely competitive contest, setting up a fascinating second leg at the Nou Camp next week.
"They're a top-class team and it's not easy to press like mayhem but afterwards we did so, so well and credit to the boys for that," the Scotland international told BT Sport.
"We're Manchester United, you can never write us off. They've got top class players but so have we."
