With Lamin Yamal incredible rise to fame and Mbappe joining real Madrid Laliga is about to witness another level of rilvary between real Madrid and Barcelona. Barcelona might still be struggling with their financial situation currently but I think they are going to fight for the league next season. They have some good players in their roster who can make the difference and if they can successful bring in few players to complement the ones they have right now I think it will go a long way. Their new coach might be new to the Barcelona but he is not new to football management, he knows what he is up against and anything less than competing for the league next season and qualifying for the champions league will be a failure for the club. Although I still see Real Madrid as the favourite to win the league.
Real Madrid are undoubtedly the favourite of next season's Liga. Barcelona has a chance but they have a lot to do in this transfer window. They've started by hiring Flick but they still need a lot of reinforcement in defence, midfield and Attack. They also need a backup keeper that will give Ter Stegen competition.
They're going for Nico Williams and they also need a solid DM. They need another CM or CAM because Pedri and Gavi are injured. If Barcelona can make 5 proper signings that will strengthen their team, then they might have a big chance of winning the league ahead of Madrid. They have a good coach, but without backing, he won't be able to do anything.
What I'm certain of is that the season would be competitive that's for sure.
