Fenerbahce doesn't look like in a very bad condition. If you learned their stats in the last few matches, they performed quite good. Although they got a draw against Twente and lose against Galatasaray, I think it is still acceptable. But Man United performed badly, they often got losses and draws against small teams. If we look at this condition, it is clear that Fenerbahce will be in a better condition. Moreover the next match will be in Fenerbahce home, Fenerbahce probably won't miss the chance to get full points. So, I also agree that Fenerbahce should be the favorite team to win the upcoming match in Europa league.

I would say don't fall for those statistics.
Because the game they have played so far is really not that good. They have serious problems on especially defending. But they have been quite lucky most of the time so far that it didn't cause them to lose more points than that. But this can't go on the same forever of course. Livakovic can't be the hero in every game they play...But when it comes to the Manchester United game, I think Fenerbahçe might not lose any points. Because they will have a really troubled opponent on the pitch. Do you remember how Galatasaray beat the Red Devils at Old Trafford last season by the way?
It was an incredible effort.
