With 10 players still injured, it certainly won't be easy for Manchester United to beat Real Sociedad, even though the match will take place at Old Trafford. Ruben Amorim, with limited rotation options, must still demand his players to give their best performance. If they can repeat their performance like when facing Arsenal, chances are luck will be on the side of The Red Devils.
Except Manchester United's players didn't perform well tonight, I don't believe having 10 injured players missing will stop them from eliminating Real Sociedad in the Europa League. Real Sociedad is also struggling in their league, losing their last match against Sevilla, while Manchester United was able to draw with Arsenal. So, if they can maintain their performance against Sociedad, I believe Manchester United would have a better chance of winning.

Big game today for Amorim and his boys. Manchester United will be taking on Real Sociedad. Both sides have a little history in their head to head meetings, and in their last two meetings before the recent first leg tie they have recorded very few goals. Both sides seem to be similar in performance level which has been proven once again in their 1:1 draw. However, in the second leg Manchester United have an advantage since they will be playing at home, I really hope they can utilize this opportunity to get a win.
I hope Manchester United uses their home advantage to defeat Real Sociedad in the second leg, the competition would be less interesting if Manchester United is eliminated in the round of 16. I only see Manchester United as a big team in this competition. However, Manchester United performance can be inconsistent, and whether they play at home or away, they can lose a game at any time. Let's see whether the guys will achieve this for Amorim tonight, after Arsenal failed to beat them over the weekend.
