Manchester United defender Chris Smalling believes that his side can cause an upset at the Nou Camp.
United have it all to do in the second leg of their Champions League quarter final with Barcelona. They are 0-1 down after the home leg, which means a narrow win is the least they must do at Barcelona to progress.
But Smalling is confident, given United's away form in Europe this season.
"We know it can be done," said the England centre-back said to BBC Radio 5 Live's Football Daily podcast.
"If we can carry on from the second-half performance when we were really on the front foot, brought intensity to the game and caused them a few problems, that's what we need to go there and do.
"We knew that we couldn't go completely gung-ho in that second half because there is another leg.
"We've got to make sure we go there with no regrets and leave everything there to give ourselves the best possible chance."
