Mbappe has much more experience compared to these young players, but the problem is that Mbappe can not cope with the pressure that is put on him in Real Madrid, and from the fans and perhaps with the failures that he faces in the team. In Monaco and PSG he was a leader, in Real Madrid it seems that he does not have such a status and is unlikely to be able to get it, so he will have to go through all this, and this will determine whether he can become the leader of the attack of Real or not, so far Ancelotti believes in him.
I don't want to believe that Kylian Mbappe's struggles since he arrived Real Madrid is caused by pressure. When the France international was still with his former club Paris Saint Germaine, he was sharing the pitch with the likes of Lionel Messi and Neymar but he still delivered great performances. I want to believe that Mbappe's inability to live up to the expectations of many might be caused by something beyond the reach of the public but I believe in the abilities of the France national team captain and I believe he'll bounce back to his best in no distant time.
