I don't even know why AC Milan considered to sell him considering the fact that he was just bought at the starting of the current campaign. With Osimhen already braised to leave Galatasaray and also with Icardi absence from football due to injury, it is wise for Galatasaray to reinforce their squad to make sure they maintain their competitive edge in the league. Their decision to sign Morata might be strange when you consider that he is 32 years old, he might not be able to play for long.
Milan has been trying to sign Santiago Gimenez from Feyenoord if you haven't heard. They must have made serious progress on the signing otherwise I wouldn't expect them to let Morata go already now. There are Tammy Abraham and Luka Jovic as well in the squad maybe but they don't look even as reliable as Morata. But I can't say Morata is a great CF either.
At least he makes bigger score contribution and can be useful for Galatasaray when Osimhen's loan ends.Galatasaray should actually focus on improving the defense line with new signings instead. And when it comes to Osimhen situation, they say Galatasaray made an offer of 65 million euros but rejected by Napoli. They want 75 million just like in his release clause.
