I think world football has struggled to produce talented strikers in recent years. The compact football mentality reduces the number of players who stand out with their individual skills. So, even if Osimhen doesn't perform very well at Galatasaray, there will be clubs who will want to sign Osimhen because the number of players like Osimhen in world football is decreasing day by day. Stars like Osimhen, Haaland and Mbappe are players who can single-handedly change the score and the game when the team is bad...
You are right about that too actually. Because you know the Turkish league isn't best place for quality players such as Osimhen to show their skills in the best manner. He can still perform better when he is signed by a much bigger team competing in one of the best European leagues.
Chelsea and PSG seem like the biggest candidates for now. Galatasaray fans were worried about losing him in January too actually but they must be relieved after hearing that there is no such condition on his loan contract.
Adrien Rabiot is without a team for more than 2 months. He is still dealing with his mother's desires about his future. What a pity! If he wasn't under the influence of his mother in his career, I believe he would have been in a much better position now...
