With realmadrid recent form this season I think adding up a quality player like kylian mbappe will be a great move for the laliga champions. To me kylian mbappe will be one of the best signing next summer, he is a very quality, he has alot of qualities that build up a best player, his pace, his exceptional goal scoring pattern, and his skill. Concluding everything I think he is one of the best young player that have ever seen in football history.
In addition, Madrid will also benefit considering that in the current season they are so difficult to score goals when Benzema cannot play for them. Their goal productivity comes mostly from Benzema and when he is not able to play Madrid's form has slumped so badly that they need at least one new striker who does have good productivity.
Mbappe is the one who is suitable for this because at least with this Madrid can breathe a sigh of relief when Benzema starts to slack off or can't score goals for them
Mbappe is surely not going to be a rotation player for Real Madrid if that is what a lot of people are thinking. He is going to be a crucial player for any squad.
So, if anyone is thinking that he will be a replacement for Benzema I think they are quite mistaken. But I really think that if he plays in the right wing and Benzema is the main striker Real Madrid is going to score a lot of goals. Now Real Madrid really needs to buy a good defender that has a really good pace.
