Just beating Real Sociedad - let alone by two clear goals - will be no easy task.
They have won all five of their games in the Europa League so far, conceding just one goal.
Erik ten Hag is well aware what his Manchester United side must do tonight:
"It's clear," he said. "Obviously it's important we win. We know what we have to do: two goals difference.
"But we like these challenges. If you want to win a trophy, you have to beat everyone.
"It's difficult to win games here, but we have a plan for that and we will do everything to get it done.
