Manchester United's chances of going trophy less or not will be determined today at the end of the game at old trafford. Manchester United where considered favorite to win the Europa League if not for injuries on the likes of amad dialo and Martinez that made Manchester United lose balance a bit. But looking at their last performance against Real sociedad and arsenal, they still stand the chance to win today's game against Real sociedad
Real Sociedad have not been on their best form in both the Europa and their domestic league so I have the same feeling as you that Ruben Amorim will qualify for the next round. So far, Man UTD have been going through this competition by sheer luck and few goals, and it's not like they will find it easy from their visitors but being that they (Real sociedad) have got their own challenges, Man UTD will try to capitalize on this and get the necessary win.
Man UTD are operating the same way in their league, getting by through scrapes but the difference is there is still time to redeem their self in the domestic league unlike here where any wrong move can prove costly so I have the feeling that they will do all they can to win today's game.
