Transfermarkt.com shows 3 teams in the list but we know there are other teams interested outside of that list and I hope Liverpool can secure his contract because I want to see Osimhen compete in the Premier League. Besides that, Liverpool need to prepare a replacement for Moh Salah who predicted to move/retire 2027

Actually I have never taken too seriously regarding the rumors of transfermarkets.com. Because sometimes the results are uncertain. But at least with these rumors we can trust more if Osimhen has a greater chance of joining Liverpool. And related to Moh Salah, it seems like Liverpool have not found who is worthy to replace his position.
I personally also fully support if Osimhen can play at Liverpool. Because I personally also regret that a talented player like Osimhen has to play in a league that can be said to be not too tight. So Osimhen should be able to play in a higher football league like the English league. Because he is still young and also has a very good performance. So if Osimhen plays in the English league or more precisely at Liverpool, I think Osimhen will have no trouble competing with other great strikers in the English league. So I really hope Osimhen is really brought in by Liverpool, because after Osimhen moved to Galatasaray Osimhen's name slowly faded a little. Even though when he was still at Napoli Osimhen really became a star there. But because of the personal problems he had with Napoli that made him what he is today.
And besides that, Liverpool really have to immediately find a player who can replace Moh Salah. Because if it is prepared from now on, I think the results will not be too disappointing when the time comes for Salah to leave Liverpool. Because currently Liverpool only have 2 right wingers, namely Salah and Chiesa. So if Salah leaves Liverpool, I don't think there is a really good replacement. Because Chiesa in my opinion is not comparable to Salah and he is also approaching 30 years old. So I think Liverpool really have to pay attention to this. But it seems like Liverpool hasn't really bothered about this. Maybe they thought that next season would be a better time to think about this.
