In my opinion, Victor Osimhen is a more talented center forward than Halaand, that's a fact. English teams have stayed away because of Napoli's transfer fee, but if Galatasaray performs well in the Champions League and Osimhen contributes sufficiently, then English teams will be lining up to sign him. The Galatasaray squad is quite ambitious this season, so Osimhen isn't alone, so he could produce better results.
Surely you said Victor Osimhen is more talented than Erling Haaland? are you kidding how Halland achievement so far winning UEFA Champion League and Premier League with Manchester City but Osimhen only won Scudetto only so far.
No doubt Haaland is most talented forward than Osimhen and consistent become top scorer in premier league last several season, lets see Osimhen with Galatasaray performance in Champion League will reach higher round or eliminated early since phase league round. For Manchester City as favorite team in Champion League indeed last season have eliminated at knock out round and get failed in domestic league, but this season after several top talented recruitment I believe City have bigger potential.
