I see Manu as the strongest candidate for Osimhen. Chelsea did not buy players for such astronomical amounts after Abrabomovic left the team. I don't think they can either.
Arsenal or Manu can buy him. Manu is the strongest candidate because they have had terrible seasons in recent years.
They need to build a good squad for next year. Arsenal can also because Arsenal doesn't have very good strikers either. Havertz is both injured and has never been a player with a very good goal shot.
I don’t think the issue of Manchester United have been about strikers. The mentality of the team has been their greatest demise.
That’s not the case with Chelsea and Arsenal who are completely lacking in that. Though Manchester United might be the strongest in line for him, he would be a better addition to either Chelsea or Arsenal. Both these teams need a proper striker that can be at the end of those ball within the goalkeeper box. VO9 could connect and convert, his good for it.
