Let me shock you Manchester United may not win the match if care isnt taking. And the bookmakers are also speculative when it comes to odd decision making. I wont agree that they know more than us.
Real Sociedad is not okay this period and even if we assume that Manchester United is sick then I will be surprised to see Real Sociedad outperform them in tomorrow's game. Their last match was against Sevilla and they lost it, they were humiliated by Barcelona in the last days. Manchester United got a draw in their last match against Arsenal which is very good in the my opinion.
I will go with the team that fails its supporters the whole time, Manchester United!
Both Manchester United and Real Sociedad are not ok this period and their performance this season is enough reason to prove that both teams doesn't deserve to get to the stage there they are right now in the Europa League competition but seeing how they have been playing poorly in their different league one can not pick the better side because Real Sociedad has lost so many games league lately and Manchester United has managed to secure draw but there is no change in their game play. Manchester United will play host to Real Sociedad regardless of their performance against Arsenal I still don't have enough conviction that Manchester United can win the game as they concede goals easily after scoring.
