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.
Maybe Real Madrid will undoubtedly be the club that dominates La Liga in the coming season. Because Barceloan and his new coach still can't be sure whether it will go well or not. Because we have seen enough times that changing coaches can cause a club to experience setbacks. And yes, sometimes it can also make a club progress. Actually, I still quite regret that Barcelona lost Xavi. But I also hope that Flick can make Barcelona even better. Only in the first season maybe it will be a little difficult. And hopefully the club can be patient if the first season doesn't go as expected. La Liga is always competitive, even last season Girona surprised everyone. And I think other surprises will also come in the next season. It's just that it's quite difficult to imagine that any team will stop Real Madrid from winning the title next season. Because the current depth of the Real Madrid squad really looks very convincing to me.
