Lautaro Martinez is an incredibly good striker. But I personally don't like his finishing. Lautaro Martínez could improve a bit if he goes to another club. Because I think this player deserves to play in another good club.
Inter Milan is not hesitating in their performances; they are doing everything in their position to attain satisfactory outcomes. The Argentine's performance is essential as he is constantly ready to position himself in front of goals. He deserved to start a new career someplace else, perhaps in the English Premier League or Laliga, where he could get new experience rather than staying with only one Italian club. Lautaro Martnez has remained Inter Milan's only constant frontline player, and his presence is vital to both the team and the fans.
Lautaro Martinez himself still has a fairly long contract at Inter, so I personally not so sure that Lautaro Martinez will leave in this transfer market. After all, playing at Inter and in Serie A is not something bad at all, because Inter is one of the big clubs in Serie A. Also, regarding Serie A itself it is still considered a competitive league so yes, it would not be bad at all if Lautaro Martinez still plays here for the next two seasons or maybe until his contract expires.
it is true what you said that Lautaro Martinez could appear strong at Inter Milan even though some people considered the team from series A to be a competitive team but at least Inter achievements could reach the champions league last season even though they lost but it was not easy to reach the final and like Real Madrid which is famous for its strength in the champions league can be defeated by Inter Milan and this is all thanks to the performance of Lautaro Martinez.
Inter Milan I don't think it's necessary to sell him until his contract expires because I believe Inter will soon get achievements in the summer with his reliable players and I also believe that Lautaro Martinez can still make a good contribution at Inter Milan.
