The Red Devils will go into next week's game against Real Sociedad knowing that a win by two goals or more will see them avoid a play-off against one of the teams dropping out of the Champions League.
Although, for much of the first half, it didn't look like that was going to be the case. The hosts were regularly thwarted by their opposition before Diogo Dalot was able to ease worries with a well-placed header on the stroke of half-time.
After the interval, it was pretty straightforward for Erik ten Hag's side as they were never troubled by the visitors. It took a while for the second goal to come but it was worth the wait as Marcus Rashford sent a thumping header into the back of the net from fellow substitute Luke Shaw's perfect cross.
At that stage, the only thing the evening was missing was a Cristiano Ronaldo goal after he had been restored to the starting XI. He missed a few chances - including a sitter in the first half - however he finally got on the scoresheet as he reacted quickest after Maksym Koval kept out his initial header. A big moment for Ronaldo there - but maybe not enough to convince anyone he's back to top form.
