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.
I know yamal was incredible at the Euros and the kind of England team they played against almost looked like a typical real Madrid team but I dont see Barca doing better than real Madrid this season. If nico Williams joins Barca then it will be a very interesting move that will make laliga more interesting but it's still deficult to see another team that can come close to real Madrid at the moment in terms of individual brilliance and the spirit and energy that comes from playing at the Santiago Bernabéu is just one incredible thing that always stands as rhe 12th support syatem for the madrid team. Barca can't rely on the young yamal as thier only strength in the coming season, they need to sign new players that will pair well with him, Lewandowski and christiansin. A collection of experienced players and young, hungry and talented players like yamal and nico Williams, if he will be signed before the season starts in full swing will be the only way to give real Madrid hard time in the coming season.
