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.
What Mbappe said seems to make sense, because indeed we can see how the performance of Madrid's attacking line is not optimal at the moment, in some of the matches they have played it is indeed seen that Madrid's attacking line does not have cohesion and chemistry that is good enough so they do need improvement and also work to achieve perfection in their attacking line, The difference between Real Madrid and PSG is quite significant especially in terms of pressure and also the competition that exists in the league, when at PSG, Mbappe is the main star and he is supported by great players in the farmer league who indeed have no competition at all because the quality of the team is much different so far, but in Madrid, of course he must to adapt to a different style of play and also compete with other quality players including the competitive league is obviously making his difficult at the moment.
