So far Kylian Mbappe has always been linked with a move to Real Madrid. It's true that Mbappe deserves to be there, but I believe the team that has the potential to win the Champions League title is not only Real Madrid. Kylian Mbappe could move to the Premier League for a team like Liverpool, Manchester City or Arsenal, but La Liga would be better if Mbappe joined Barcelona.
If Mbappe plays in Laliga why does it have to be Barcelona when Madrid is much better than them and has a chance to win the UCL title this season compared to Barcelona, besides if we want to talk about opportunities of course we know that all clubs have a chance to win the UCL this season, but usually the strongest club In the UCL currently, from my perspective, there are only three clubs, Manchester City, Munich and Madrid.
I don't mean to badmouth Barcelona because I think Mbappe won't be a surprise if he plays there, the possibility of playing in Madrid would be very appropriate, especially in Manchester City if he really wants to play at an EPL club compared to other EPL clubs, but we'll return to his decision later where he will play, because PSG is no longer the right club for him to stay and get the UCL title.
Madrid is far more better for him if he wants to be in the La Liga by next season because they are the team with the kind of potential he sought, amongst all other teams in La Liga, Madrid remains one team that can stand confidently enough to contend other teams regardless of how well they are in their various domestic leagues, Barcelona may likely keep his shine within la Liga but Madrid wouldn't.
Mbappe needs a team they will bring him to the peak of his career while achieving so much together, Barcelona mostly get better chances with la Liga but with Madrid he will get better chances both with champions league and laliga, he would also get a chance at balloon d'or in the nearest future so I strongly believe Madrid still remains the best bet for him. If he eventually wants to go to an English team, Manchester city will be the best team to help him achieve his dreams better than he would with other premier league teams.
