I heard rumors about Real Madrid's interest in Julian Alvarez who is currently still playing for Manchester City. The Qatari World Cup winner is said to be a worthy successor to the aging Benzema, but several other players have also been rumored. Osimhen is good, but I don't know if Real Madrid will really go after him.
Real Madrid are really looking for the best number 9 player to replace Benzema, so some of the names mentioned above might really be the targets they will strive for next season. Haaland must be tough, I think he'll just enjoy the best of seasons at Manchester City even if Real Madrid are able to activate his release clause.
I think it is only a rumor, Man City won't let Julian Alvarez moves to any club. Julian Alvarez is an important part of Man City, he already contributed many goals so far. I think Real Madrid will try more to sign a player like Osimhen or Harry Kane. These players deserve to be the successor of Benzema, they also have a better chance to move because their contract expires in 1-2 years. While Julian Alvarez's contract expires in 2028, there are too many years left. So, the best successor for the number 9 of Real Madrid striker should be Osimhen or Harry Kane. Haaland won't move anywhere, he is happy in Man City.
