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.
He is definitely going to be Trabzonspor's best player. If he can join the team in the playoffs, maybe the playoffs will not be too difficult for Trabzonspor, as a team they are quite strong, the opponent may not have the ability to beat them, especially after Salah's addition.
If I talk about this whole tournament, then even after Salah's addition, I don't consider them favorites, although they have not yet qualified for the UEFA Europa League. Even if they do, they are not favorites for the title. AC Milan and Juventus are in this league, so they can be considered favorites for now.
