Almost every team in the Premier League needs Victor Osimhen, but Chelsea was the club that had the opportunity to sign him before he went to Galatasaray on loan, and I am sure they are making huge reservations for him because with the type of momentum Chelsea is performing with this season, I think if they can get Osimhen, it will be a plus for them.
We don't know that Chelsea will have a higher chance to sign Osimhen. It purely depends on Osimhen, where he prefers to play. It is not impossible that he may choose La Liga or Ligue 1. Besides the top teams in EPL, I also heard the rumor that Real Madrid and PSG are interested in signing Osimhen. Osimhen is still favorite striker, there are still too many teams expecting to sign him.
However, if Manchester United can get him, it will be a good move as well because the team needs a solid striker since the two strikers Ten Hag signed are not performing really well in the EPL because the Premier League needs a striker with strength and goal-scoring ability.
I doubt if Man United can sign Osimhen. Man United isn't a team that looks very convincing to win big titles. A top striker like Osimhen must prefer to choose a bigger team in EPL. Arsenal, Chelsea, Man City, and Liverpool are a better option for Osimhen if he wants to have a career in EPL. He shouldn't want to risk his career at Man United.
Furthermore, if Arsenal can get him, they will be a complete team, but Arteta and Arsenal fans, including me, prefer Victor Gyocores for now due to Arsenal's style of play.
Arsenal target is Victor Gyökeres. They probably won't change their target to Osimhen. As long as there is a chance to sign Victor Gyökeres, they seem to make it as the priority.
