I'm worried again about my club Galatasaray's chance in the Europa League now. There is still something ambiguous that's why I feel that way.
We haven't signed a left winger and a midfielder before the deadline for squad registration of the EL. Now we won't be able to register anyone until the end of league phase. I'm really happy with Osimhen signing on the other hand. My only worry is whether he will be assisted well meanwhile. I'm hopeful about Mertens for that job.

Old teammates are reunited here again!
Dries Mertens will play as a left winger, Hakim Ziyech plays as a right winger. I think Galatasaray coach will use this duo players for the wingers. But it will be quite confusing if one of this players got injured. There is no more option for a left winger if Mertens injured. Well, I can understand that Galatasaray has too many right wingers, they have no pure left winger.
However, it is good that Galatasaray signs Osimhen. It is a food addition player for Galatasaray. With 4 strikers in the squad, I think Galatasaray coach may use an option to play with 2 strikers.
Mertens is a fantastic player, but at 37 he is not becoming younger. On that left wing, they need a backup plan; Barış Alper might be the solution. He's youthful, energetic, and possesses that natural width. Ziyech on the right is rather excellent. Thats a move that makes sense. Though Galatasaray is not his final move, Osimhens is a great striker. He has potential to be among the best; premier leagues throughout Europe are calling. Should he choose to realise his own potential, he might have to weigh those choices downstream.
For now, though, let us concentrate on what Galatasaray has. They are in this to win; they have a fantastic coach, a terrific squad. Believe me, this club is going to make a lot of noise this season.
