Kareem Benzenma is one of the greatest strikers. His style is impressive, and he plays fantastic football. His return to Europe will be good for him because, in Saudi Arabia, he is facing a lot of criticism from their club fans.
No doubt, Benzema was the iconic player and effective machine goal of Real Madrid. Although he is not really popular with France national team, but he is very famous in Real Madrid because he performed impressively. However, I really don't expect to see him again in European league. He already noted great history in Europe, don't ruin it by speculating to play again there. If he played badly, there will be always criticism wherever he plays. Even, there will be more criticism if he played under performance when he returns to the European league.
I think Chelsea is one of the clubs that have taken an interest in the Kareem Benzenma transfer, and a move to the Premier League will be better for him than returning to Real Madrid. Real Madrid is a big club, and they need a striker who's got strong strength and stamina. Kareem Benzenma has become old, and he will not do the job correctly for real Madrid. So I think Chelsea will be good for him because in the Premier League, a striker only needs to focus on hitting the ball and not on the team's play, whereas in real Madrid, you will need to make a chance for other players.
Both Real Madrid and Chelsea seem to have no serious intention to sign Benzema. There is no big advantage to have him in the squad. Benzema even failed to play well in Saudi, how can expect him to play well in Europe? Real Madrid focuses to sign young strikers, their targets are Mbappe and Osimhen. Meanwhile Chelsea already have Nicolas Jackson. Chelsea also prefers to sign young strikers.
