I'm sure it will be Barca with Lamine extraordinary performance, as for Real Madrid, They have a bunch of stars but I feel they aren't gonna coorperate and they wont be good chemistry among them.
Why do you say that at this time? Are you not sure that Ancelotti's coaching at Real Madrid is generally still able to reduce every player's ego? Because I don't think Real Madrid will be bad because there are more stars in their squad next season, although I also won't deny that Barcelona can be quite good with players like Yamal still in their squad next season. Barcelona fans are just hoping for the best for Barcelona next season because the coach is different, while Real Madrid will still be handled by a coach who is experienced enough so it is very unlikely to be worse than last season.
