There are even many more names who aren't mentioned here. Batshuayi is already signing for them though. Wan-Bissaka is another name who is close to joining them. Truthfully, it would be a wonderful right-back transfer for Galatasaray. He is still a young and skillful player. They can use him like an offensive back especially.
McTominay rumour is also pretty interesting. If they finish this transfer too Galatasaray midfield would level up surely. He can be useful in various positions of the midfield.
Fenerbahçe made a big noise by bringing in Mourinho. Galatasaray, on the other hand, have been quiet in the transfer window but have been filling the missing areas with the players they need. Batshuayi is one of these transfers. A spot on transfer for Galatasaray who want to strengthen their forward line next season. I don't understand why Fenerbahçe didn't want Batshuayi. He has a good goalscoring percentage and if he plays consistently for Galatasaray, he is an important candidate for top scorer. Most of the players on the list are the ones who will help Galatasaray dominate the league and stay in the Champions League. Wan-Bissaka would be the right player for the right back transfer.
