I have said this before and am equally going to say this again, if I were to Advice victor osimhen on his next move, I will definitely advice him to stay put at Galatasaray because the love he has been showered with and how desperate they want him speaks volumes that this is were he is greatly appreciated, loved and cherished, so moving to somewhere else might not go as planned, and it may affect his form on the longer run if he goes somewhere else and doesn't start performing right away, so doing everything in his power to stay at Galatasaray is the best option to me if I would be advicing him on his next move.
Leaving Galatasaray would be a tough decision for the striker but if he does, he'd be missed and a lot of people from that region who love him so much would watch his matches wherever he goes. Yet, the fame and hospitality fans showered on is something that's meant to keep the Nigerian in Galatasaray. Also, it'll be somehow to find him substituted when entering a competitive game like premier league, he should stay where he shines and makes wave globally. Moving around to other club indeed shows competent, but atimes it doesn't favor every star.
