I expect the same thing in Mbappe career, if he moves to the EPL then Mbappe will form a new axis with Halaand, like the era of Ronaldo and Messi in La Liga. The competition between the two in one competition will become a topic of comparison, who is better than the two. However, we all know that Madrid is number one to get his signature, It seems like Mbappe chances of moving to the EPL are very small, last summer Liverpool, Chelsea, Arsenal and Man United were reportedly interested in recruiting him.
It is difficult to imagine PSG performance if Mbappe left them, even though they will still dominate Ligue 1, it will be very difficult for them to win the European Champions League. I think this speculation will be answered next season, when the transfer market opens and Mbappe will decide his fate.
Currently we have lost a mega star who was able to create competition regarding quality in any league, as we saw when Cristiano Ronaldo and Lionel Messi were in La Liga. Mbappe will continue to be linked with Real Madrid because the player himself also said he wanted to play with Real Madrid if he moved from PSG. But I also want to see Mbappe and Haaland's competition in the EPL because it will make their competition and rivalry more prominently discussed even if though there is little chance of Mbappe moving to the EPL after his contract ends at PSG.
It's not too difficult and if they want to chase the Champions League trophy, they have to build a squad like the one Manchester City has and it's impossible for this to be achieved instantly. In the future, they also have to get used to being without Mbappe so that when he leaves it doesn't make this squad worse in Ligue 1 or the Champions League. It requires preparation with young players and their finances should be able to make the project run well like what Manchester City did.
If Mbappe leaves the club, he will surely choose Real Madrid as his next destination. Before this, there were several rumors of transfer between Real Madrid and Mbappe, but due to the lack of Mbappe's right decision, the deal was not successful, but if Mbappe leaves PSG in the future, then he will definitely come to Real Madrid and Real Madrid will accept him. Mbappe was offered a big offer by Liverpool in the transfer window but we heard a rumor that Mbappe rejected the offer. Even if the rumors are false, I still think that Mbappe will not go to the English Premier League, instead he will go to La Liga to play for Real Madrid.
