Galatasaray is fighting to at least advance to the next round of the UCL. Therefore, the Osimhen transfer is of critical importance. A deal with Napoli hasn't been able to be finalized, and they're fighting to make it happen. The Napoli president is constantly pushing the limits, but Galatasaray is focused on completing the transfer.
UCL has not started so we don't say they are struggling or having a hard time yet, the new format has made it unique such that even the least favorite teams can advance to the next round. Last UCL, we saw some big teams leave during the first round, they still stand a chance without the player but in order for them to succeed at ease using a prominent squad, they need to finalize the deal with Osimhen.
Napoli are making the deal too difficult to complete, seeing how desperate Galatasaray are for the player makes them refuse to reduce price for the player, but i believe Galatasaray are going to make the deal come true no matter how hard the process.
