Osimhen will have to take a pay cut in order to facilitate a transfer. He probably wants to play for a top team in one of the top European leagues but in order for that to happen both the club and the player must make compromises.
Yes, but he is not willing to accept a pay cut, and only few clubs are interested in him at moment. He's still in Lagos for the holidays, playing football with his friends. Don't forget that Gala has also made an offer to sign him permanently. (about 250k/week)
He won them the La Liga and the CL. Pretty sure rebuilding Man United would be a tad bit easier than the things he went through at Real Madrid.
He won the league with us as well and led Everton to the top 3 after 10 games; he nearly formed a winning-squad at Everton before Real Madrid took him away. I'm sure he'd love to return to club management; he's just what they need right now.
