Ole Gunnar Solskjaer's side will be eager to get some silverware this season and Europa League is the perfect competition to fight for one.
The Red Devils won the competition under Jose Mourinho in the 2016/17 season and midfielder Fred has spoken openly about the desire to win it once again.
Fred told Inside United: “I think it's going to be a great game against Real Sociedad, they've been having a great season in Spain.
“We know to expect a difficult game, but we're going for the win.
“We want to win the Europa League. We know how important it is to us, so we'll do our best in the game and have our best season in the Europa League so we can lift the trophy."
The knockout stages starts off in Turin where they face a Real Sociedad side with former winger Adnan Januzaj and ex-Man City playmaker David Silva.
Tips
Score prediction
Cannot look beyond Man United winning this match and end their winless run against Spanish opposition.
Real Sociedad may be able to put up a fight but their lack of conviction in front of goal in the Europa League could haunt them tonight.
Real Sociedad 0-2 Manchester United - 10/1 with Betfred
Who are you backing for first goalscorer?
For United, I see three possible contenders for this: Bruno Fernandes, Marcus Rashford and Mason Greenwood.
Fernandes has scored 19 goals so far this season in all competitions including four in the Champions League making him a suitable candidate to find the net at 7/2.
Half of Rashford's goals have happened in European fixtures this season with six. He's 9/2 with Betfred.
I'm putting Greenwood up for debate purely on the basis he has just signed a new four-year contract at Old Trafford and may repay that faith in Turin tonight. He's an outside shout at 5/1.

For the "hosts", their main goal threat comes from Mikel Oyarzabal who is Real Sociedad's top scorer with 12 goals - none coming from the Europa League and five coming from the spot alone.
Their top scorer in Europe's second-tier competition is Jon Bautista with two goals - both coming from off the bench against Croatian side HNK Rijeka.
The Spaniard is 7/1 to find the net but I would be surprised to see him feature as he has been an unused substitute in half the group stage matches.
