The Reds go into next week’s quarter-final second leg in the Catalan capital 1-0 down after a winner officially recorded as a Luke Shaw own goal, when the United defender deflected a Luis Suarez header off his arm into the net in the 12th minute of the Old Trafford tie.
Yet United have pulled off some stunning Champions League wins away from home this season.
Last November, in Turin, we shocked Juventus in their own stadium by winning the group match 2-1. And, famously, last month, Ole Gunnar Solskjaer’s side went to Paris to pull off a remarkable 3-1 win against PSG to progress to the last eight on away goals, having lost the Old Trafford leg 2-0.
