Real Sociedad wins or ends in a draw.
I do not know Manchester United is an excellent team, which leads us to say that it will surely win the match and all the shares are in their favor, but I think that the shape that the Real Sociedad is having can put Manchester in difficulty, surely they are better in the championship and this is a fact
The result is as I predicted (1-1) and I believe even though the 1 score that Real Sociedad has is like luck, but Real Sociedad's performance is much better. And it is true what you said if at least Man United will have a hard time facing Real Sociedad.
The second leg will belong to Man United.

The odds for the
Fenerbahçe - Rangers game is like below.
Technically Rangers had a better league phase. However they still looked really poor in the games against bigger teams such as Manchester United and Tottenham.

Looks like what you said came true mate. Rangers were much better scoring 3 goals with some really good finishing. Odds @5+ really trap us to believe in Fenerbahçe. A little disappointed with this result.

BTW, Roma vs Bilbao match was really interesting. Both teams gave each other a fight. Dovbyk had 2 chances and the first he had to slip when he wanted to shoot the ball and the second chance Dovbyk's shot hit the Bilbao crossbar. I believe the match will end in a draw.
