Who would have said that we would watch Salah at Trabzonspor as of now?

He is officially a player of them now for 2 years.

So this means that we are going to watch one of the superstars of football history in the Europa League this year. League phase isn't guaranteed for them yet though.
But if he is registered for the squad of playoff round then I expect Trabzonspor to reach league phase no matter they face Ferencvaros or Gornik Zabrze first. They are much stronger than both technically.
Ferencvaros or Gornik zabrze are team that trabzonspor should be able to win and progress to the league standings of the UEFA Europa league even though Mohammed Salah is not available, but I guess that he may feature in both games if he has already resume training with them, because trabzonspor wouldn't want to take a risk by not featuring their best player in the game. Mohammed Salah is going to add a lot of quality to this trabzonspor team, and if other part of the team is not that porous, I believe that they are really going to do well this season.
Salah is already match-ready. We saw him play for Egypt at the World Cup. He took a vacation after the tournament, but a footballer's vacation isn't like ours—just lounging around, eating, drinking, and swimming.
These guys have to live like professionals.
He is also training with Trabzonspor.
I think we’ll even see him on the pitch for the league match this weekend.
Salah will play in the play-off match. Even if he didn't—well, Trabzonspor is strong enough to eliminate whoever their potential opponent might be—but Salah will be out there on the pitch for those games.
