The rumors was not true, because Victor Osimhen never want to leave Napoli to AC Milan than to leave Napoli to premier league club but their manager has increased the salary of Victor Osimhen, which victor Osimhen have to think very well not to regret of leaving the team to another team when his contract is not yet expire. I think, AC Milan need a young talented strikers in this summer so that they will not experience what they experienced last season in the Italian league competition, but I don't think their president have any budget for that in this season and it will really affect the performance of AC Milan in this tournament. I believe Victor Osimhen will not leave Napoli in this summer than to wait to help the team to win another title in this season before he can join premier league team, because that is his next move.
Impossible rumor with Milan want to sign Victor Osimhen from Napoli, I don't think Milan have enough money for paying 100 million euro or above from this values for paying fees transfer. Usually AC Milan is the teams interested for signing players not get regular position in their teams with lower fees transfer. Current Milan transfer activities, most player signing after their contract have been over and easily signing with free agent without paying transfer fees.
Its not difference level and player composition between Napoli and AC Milan, I think Victor Osimhen will prefer staying with Napoli than move to AC Milan will difficult chance winning scudetto next season.
Ac milan has brought in several quality players this season such as pulisic and several other players. So the issue linking ac milan with osimhen is just a myth because ac milan will not be able to afford it at the high enough price that Napoli is setting up.
Apart from that, AC Milan is still relying on Leao and Giroud next season so there won't be a big obstacle to the depth of their squad next season. AC Milan is one of the teams that is quite active in this transfer window because they got an injection of fresh funds after successfully selling Tonali to Newcastle United.
