Why Kylian Mbappe left his old club PSG is unknown to me. I tried searching for it but failed to find it. I was kind of shocked by his decision. Because there was a bright future for Kylian Mbappe at PSG which can be deduced from the old stats. If the future cannot be determined by looking at past statistics. I heard from various media that PSG club was not willing to let go of former World Cup winner Kylian Mbappe. Kylian Mbappe left PSG on his own, but the reason is unknown to me. Kylian Mbappe was having a good time at PSG, the fans loved and supported him a lot. His performance in PSG was also great. But as a team they did not perform very well, as a result they won other tournaments but never won the Champions Trophy. But did Kylian Mbappe cut ties with his old club PSG in pursuit of the Champions Trophy?
The reason Mbappe left PSG was basically to win Champions League title. He did his best to win it at PSG but seems luck was never on the luck of PSG because I don't see anything that stopped them from winning it for several years that they assembled the best players in the world. There was a time they had Messi, Neymar, Mbappe and Di Maria in the same team yet they could not win it. Maybe Mbappe have realized that it may not be easy for PSG to win it, the reason he left for a team that have better records and chances of winning it. His decision to join Madrid have nothing to do with bad performance at PSG where he was almost worshipped.
If asked why Mbappe left PSG even though he was successful at PSG and his salary was also high. Of course this is an easy answer because Mbappe wants to win the Champions League!
In addition, Mbappe is still very young and talented. Mbappe was also born in Paris, he has defended PSG for seven seasons. In Ligue 1 he has won everything several times. He also almost brought the Champions League trophy to Paris for the first time, but unfortunately they lost to Bayern Munich in the final. He has done everything for PSG to win the Champions League but has not paid off. At the international level, he managed to win the World Cup with France in 2018.
That's why he was so adamant about leaving PSG and moving to Real Madrid because besides wanting to win the Champions League trophy he also wanted individual awards, Mbappe also wanted to win the Ballon d'Or more than once. If he was still at PSG it would be difficult to get all that.
