Manchester United will need to be at their best when they face Barcelona in front of the Nou Camp on Tuesday night.
A Luke Shaw own goal gave the Blaugrana victory in the first leg of their Champions League quarter-final at Old Trafford, but the contest was far less even than the scoreline suggests.
United failed to test Marc-Andre ter Stegen throughout the 90 minutes, whereas the visitors registered three shots on target and enjoyed more than two-thirds of the possession.
Off the back of such a discouraging home performance, it’s difficult to imagine Ole Gunnar Solskjaer’s men winning with at least two goals scored in Barcelona.
That's what's required to book their place in the last four - and some believe United are lucky to still have even a slim chance of progressing.

Ronaldinho feels although United shouldn't be written off completely, Barcelona could stroll into the next round if they find the net first.
“The truth is that Barcelona should have finished the game in Manchester - but at just 1-0 Manchester United will still believe that they are in this tie,” he said, per Goal.
“With the way that Barcelona have been playing and the amount of goals they have been scoring, I do expect them to progress.
“I see them even winning comfortably in Barcelona. It will all be on the first goal.
“If Barcelona score it then it will be a long evening for Manchester United.
“But if they [Man Utd] can score the first goal then it’s going to make the stadium nervous - and you never know what can happen then.”
Perhaps because there’s no clear favourite for this year’s competition, Ronaldinho is also optimistic of a new name being etched into the trophy.
The Brazilian highlighted Tottenham as a dark horse, primarily because of the football they can produce at their best.
“Why can’t Spurs win the Champions League?” the former Barcelona star added.
“Because they don’t have the history in the competition - or because they have never won it before?
“Every team who has won the Champions League had to win it for the first time once.
“Their result against Manchester City, who are one of the best teams and have some of the best players in the competition, showed that they can compete with the best.
“At this stage they will believe they can go all the way - and if they play as they can then maybe they will.”
