In an interview with a Spanish media outlet, he said that Mbappe along with his teammates, will have to work harder.
Real Madrid is different from PSG, Mbappe is not like Ronaldo, he is still very far away. I think he has to be able to integrate with the team and play as a team. He has good ability, but in La Liga it has not been able to make him a big star. Another problem is that the team's current support is incomplete, many Madrid players are injured. So the team's support seems to be decreasing. I think Mbappe still has a lot of time to develop, he just went to La Liga and he will improve a lot.
I think it's all about time, Mbappe is a player who has very good individual qualities but every player who has just joined a new team certainly needs time to adapt, so does Mbappe now.
And Real Madrid's declining performance this season because many of their core players are injured certainly hinders Mbappe's process to be able to adapt and contribute greatly to the team.
I agree if it is said that Mbappe must work hard especially when the situation of the Real Madrid team is not good like now, Mbappe must be able to become a player who can change the situation.
