Galatasaray made a transfer as if Osimhen's departure from the team was certain. After Leroy Sane's transfer, I don't think they will be able to allocate a budget for Osimhen. Even if Osimhen changes his mind and says he wants to play for Galatasaray for another year, they can no longer transfer him...
I don't know if Leroy Sane can create an Osimhen effect. He's a player far above the quality of the Turkish league, but I don't think he can create an Osimhen effect. Even if he performs exceptionally well, if he can't create a driving force for the team, his salary could become a topic of debate...
Galatasaray's transfer budget is around 80 million Euros. Also, it is said that Osimhen's salary will be around 14 million Euros. In order to complete it to 20 million Euros, they will arrange advertisements etc. from outside and give this money to Osimhen annually. Advertisements like Ülker Çizi.
Leroy Sane will definitely not create an impact like Osimhen, but he will increase the quality of our league.
Don't expect oshimen to stay in Galatasary come next season oshimen is more than the levels of Galatasary with all due respect to them but the fact is oshimen coming to Galatasary was a way of killing tension between napoli and oshimen, so don't think that oshimen will still be in Galatasary because napoli is just looking for the highest bider in terms of the money
