There is nothing to expect from Barcelona next season, I'm not sure they can compete with Real Madrid I mean Barcelona is behind in everything, they are still in the same problem as the previous season yeah financial problems which doesn't know when it will end. Recently I saw they brought in 3 young players from the internal academy, it is not yet clear whether these players will be used as investments for the next few seasons or simply to replace positions left by other players.
Competing with Real Madrid seems too tough for Barcelona because their rivals have talented newcomer players while Barcelona only maintains the same players without having the power to buy good players to improve their performance and their new coach is expected to be able to provide effective strategies to knock out their opponents, maybe Barcelona can still compete with clubs below its level such as Girona, Atletico Madrid, Bilbao.
However, in the competition for the title, I am not sure that Barcelona can achieve this achievement. I think Real Madrid is still the strongest candidate to win the La Liga title next season with the arrival of Mbappe. Real Madrid is increasingly confident.
