As far as Europa League group matches go, this is just about as big as it gets. From the moment Sociedad won 1-0 at Old Trafford on matchday one, the reverse fixture was always going to be the crunch game in this section.
If Manchester United win by more than one goal, they will leapfrog the Spaniards and end the campaign as group winners. Any other result and they will remain in second place. United are 23/20 favourites with Betfred to get the result they need in the Reale Arena while the hosts are 9/4 to do the double over the Reds after Brais Mendez' 59th minute penalty stunned Old Trafford in September.
Erik ten Hag's side were just beginning to show signs of recovery after their shambolic start to the season when these sides met on matchday one but they are now undefeated in eight games since the hammering at City and ultimately look like a side heading firmly in the right direction.
