Looking at the performance of both team the last time they met, the Host didn't outperformed the visitors and I want to say that Manchester United did performed so well for a visitor that they were in that game and then again they even had chance to add some more goals which would have kept them ahead and with even more advantage in this game, Manchester United this season have not been exceptional with their home games this season, although they have had some really good Europa League performance but I literally can't trust their performanc for this fixture so my anticipation will center more around a draw but hopefully they win this and make it to the next round of the Europa games.
In domestic league, Real Sociedad not performed well yet after dropping to 11th standings position and have 13 losses of 27 games, not difference yet with Manchester United performance not consistent yet until games week 28 still dropped at 14th standings position awhile. But both teams have huge ambition for winning the UEFA Europe League match keep secure for participating European competition next season by winning Europe League tittle.
Both Manchester United or Real Sociedad seems over for qualifying to Europe League or Champion League next season, but winning Europe League trophy have guarantee for participating at Champion League although finish outside from the top fourth standings place. Behind the draw result at first leg seems Man United have large opportunity for winning this match and get chance to secure Champion league spot next season by winning Europe League tittle.
