In my opinion, he should study and see about players who join Paris Saint Germain, indeed if we talk about money, Paris Saint Germain can pay him more than any other club. However, if we talk about career, I would not include Paris Saint Germain as a club that can make a player's career better. Let's see what happened to Mbappe after joining Paris Saint Germain. Indeed, he got many privileges, but he couldn't get anything special in his career, even though players would definitely want that.
Chelsea is not very good at the moment, so it is quite risky for Osimhen, Manchester United is also the same, but Manchester United is slightly better than Chelsea. If there is another club that is better and interested in him, I think he should consider that. The reason is that the situation of a club sometimes also influences a player's performance, unless the player can be at a very good level of stability, that might actually be what can take the club in an even better direction. But I haven't seen that from Osimhen.
I am more interested when Osimhem joins the English league compared to other leagues because if he is able to maintain the best playing form then in the English league it will be easier for him to achieve the best career. Chelsea is not at all a good place for him to come to now because the club's condition is very unstable and vice versa with Man United, but compared to Chelsea Man United is much better for Osimhem. If there were other clubs interested, maybe I would agree that he would be better off playing there, but so far not many clubs are willing to pay Osimhem a high price.
Yeah if Victor Osimhen join one of the vibrant clubs in England, He could surely make a good career over there but it's definitely not going to be Chelsea because for now Chelsea is unstable and needs a lot of work before they can be very confident in winning matches and with the kind of impressions that Victor Osimhen have created in Napoli, he needs a club that is already made in other for him to showcase his skills more rather than going to a club that is still struggling to maintain a good form.
Though Osimhen have become a costly player now but it doesn't mean that any club that is determined to sign him to their squad wouldn't afford him just that he needs a club that would be visible enough for him to exploit there.
