I am also very sure that if Mbappe goes to La Liga, he will stay at Real Madrid, not Barcelona. I once read the news about his dream club that he wants to play for is Real Madrid, not Barcelona at all. Mbappe is an extraordinary player, and he has been so often rumored to be going to Real Madrid according to expectations. However, it is PSG who still object to this. So, this seems like a very small possibility if Mbappe suddenly turns to Barcelona.
On the other hand, maybe the match that will be exciting is Nice vs Marseille. Nice has proven that its performance progress so far is beyond expectations, and is runner-up in the French League. His consistency is quite good in every match. On the other hand, sometimes Marseille also puts quite strong pressure on the opposing players. So, it gets a little more interesting later on. Yes, even though the French League is not like other leagues where the competition is very tough, at least for now, PSG's dominance is not as strong and strong as before.
Real Madrid is the best fit for Kylian Mbappe. Besides, Barcelona has players in that same position as Kylian Mbappe they won't want his services. Jaoa Felix is a good winger and fits up for that position quite well.
He should have joined last season but plans didn't go as plan, always, you'll have to plan for that plan that's not part of the plans.
Turning to Barcelona might be possible but still not in this case.
Gennaro Gattuso would be managing his first game in League One, after all round failures. I want to see him finally successfull with his job with Marseille. I'm hoping he gets better with his tactics.
