Real Madrid at the moment is very perfect, its just that they lack a striker and I also said this yesterday when Real Madrid was looking for a reliable striker to strengthen the attack line and achieve their target goal of getting the UCL trophy and the candidate from the rumors that I know is the player who currently being targeted by Madrid are Mbappe and Haaland. but for Haaland the possibility is very small to get this player because he is very comfortable in the EPL while the rumors about Osimhen I dont know about this rumor. but it does not matter if you can get Osimhen who is also very good because the quality of his talent is the same as Mbappe.
and regarding Josule, it seems like he is not a striker but is considered a very good backup striker because while replacing Vinicius position he always performs very well and I would agree if Joselu becomes the main player in La Liga and Viniciua becomes a second tier player in the UCL to maintain the players physicality.
It would be very tough for Realmadrid to get Halaand out of city next summer cause his contract with Manchester City is still long therefore it would cosr them more to get his signature, however Mbappè won't cost alot and they could get him on a free transfer when the 1 year contract extension he had with PSG expires next summer, negotiating a deal for Mbappé won't be very had cause he already did that secretly with Realmadrid and would really love to move over there cause it his dream club, and moving ro Realmadrid comes with lots of opportunities that would be beneficial to Mbappé.
If Realmadrid saw Joselu as the main striker they would had bought him permanently instead of signing him temporary on loan from Espanyol, moreover he's not very young and Realmadrid would need a striker that would last them for a long term, however Joselu nmight serve as a supporting striker to anyone Madrid finally gets.
