I am a person who pays a pessimistic attention to Manchester United to face Real Sociedad. Manchester United are in a wind-in-law in the domestic league even though in the European League they performed better.
The 1-1 results in leg 1 benefited Manchester United because at that time Real Sociedad acted as the host. Not that leg 2 that will occur at the pride of Manchester United Stadium can make it easy for United to be able to appear digged.
Maybe the match will continue until the extension of 30 minutes.
If you consider the match in the first Leg, you must know that Man United played better. If you checked the stats carefully, you will find out that they have more shots on target. Since they could play better in away match, we can assume they should play better in their home as well. Moreover, Man United should have a bigger motivation since they are playing at home. Sure, the aggregate 1-1 is the advantage of Man United because they will play at home in the Leg 2. You can doubt Man United but I believe Man United to beat Real Sociedad. I assume there is no need of an extension of time if Man United can apply an effective strategy.
Manchester United will really play a nice performance at their home game because if we are to judge from the first leg performance, we will see that Manchester United's performance is a bit better than that of Real Sociedad, and the game will end in a draw, which is just as you mentioned that Manchester United will be pleased to have a home game in the second leg, which will be like an advantage to them to win against Real Sociedad, so I don’t think the game will be that hard for Manchester United to win, but still it is a game; anything can happen, but I also have my trust in them to win the game tomorrow.
They have no excuses to give it they fail to defeat Real Sociedad at home, in the first leg they failed to capitalize on their 1 goal lead to seal the game and it ended in a 1:1 draw now they are hosting Real Sociedad, I expect them to perform like their lives depend on the competition because that is their only way to get the qualification ticket to the champions league next season if they win the Europa League competition.
Real Sociedad is not a strong team but for Manchester United every team is now a strong team to them because of their bad performance they shouldn't look down on Real Sociedad if they must defeat them tomorrow they should just score goals as many they can to ensure they qualify for the next round.
