Victor Osimhen is one of the top strikers in Europe just behind Haaland, he isn't the best. He hasn't proven himself in the top league and in different clubs therefore he can't be ahead of Haaland. Haaland has proven himself at different league and different clubs and they have all been the incredible display form.
Victor Osimehn is unquestionably a brilliant player, and his ascent to the position of one of Europe's top players while representing Lille and Napoli is evidence of both his talent and potential. I don't believe he will struggle to succeed in high leagues as you indicated because the Italian league is one of the top five leagues in Europe and he conquered the league, though I can't say for sure until he proves himself. He undoubtedly lags behind Haaland, who has demonstrated his value. We all thought Haaland would struggle to fit in in the Premier League, but he surprised us all by scoring 36 goals in his debut season. It is safe to assume that Osimhen is on par with Haaland if he can succeed in the Premier League or La Liga, two of the toughest leagues in the world that many players find challenging to adjust to.
Him as a striker. Victor Osimhen needs to move form Napoli or his career will remain stagnant. He has down his highest for Napoli and we shouldn't being the champions league into the conversation because Napoli can't win it out when Manchester city are this in form and we have Real Madrid planning for the upcoming season.
Considering that bigger teams are interested in Osimehn, it would be better for him to leave Napoli right now. Osimehn should really consider his options carefully before making any decisions. Players who were in their finest form and resisted leaving when bigger teams wanted them have frequently ended up in ordinary teams after losing their form. Take the case of Tielemans with Leicester City as an example. Although there is more pressure when playing for larger clubs, Osimhen must do so if he wants to advance professionally and be rated as Haaland.
Victor Osimhen need to join a club side that can challenge for the champion league trophy and as it stands it's the premier league that will best suit him. He's a very young player and there'll be room for improvement in the future as he gets to play with more experience players.
He is a passionate, high-energy player who can fit in well in the Premier League, but if they still want him, I would prefer that he move to Madrid since his prospects of winning the Champions League there are higher than when he joins a Premier League team. The only team from the Premier League that is consistently competitive in the Champions League is Manchester City, and they already have Haaland and Alvarez on their team. It is not ideal for a player who wants to win the Champions League to move to Chelsea or Manchester United.
