I don't see any risk there in Galatasaray having to spend such big amounts for Victor Osimhen getting him into their club completely. Victor Osimhen beyond doubt proved to the Galatasaray management that he is worth every penny they give out for him by helping them to winning all trophies in the Turkish football league, humbling Fernebache despite how much of a competition Fernebache pulled out against Galatasaray Osimhen was always there to save the day either by assist on goal or scoring himself. What club wouldn't sign such a valuable player?
The real risk is putting so much money on one player. What if Osimhen gets injured in his first game? If he breaks his leg or tears his ACL and misses a season, he won't be able to return to his previous form. No footballer is worth taking such a big risk. Of course, a healthy Osimhen is a serious threat. He proved that with the goals he scored last season. The player has a very high cost. It's several times larger than the annual budget of many teams in Super League.
What is Fernebache? I've never heard of such a thing in my life. There is Fenerbahçe in the Turkish Super League. There is no team called Fernebache anywhere in the world.
