I don't think Barcelona have the strength of moving around in transfer window because of their financial situation now, even before the starting of the season it should be better Barcelona to agree to just stay behind real Madrid because they can stand it, second place is for them the earlier the believe it better for them, Real Madrid are currently the most strongest teams all over the world not Laliga alone, and they are fit to play and win any of the competition without any fear. Among all the leagues, I think only home league required a consistent performance to be able to maintain it, and already they are built in that.
I agree with you. I think with Barcelona's current form and their financial status I think it will be very difficult for them to try to match Real Madrid. In fact, Real Madrid is the best team in the world at the moment and with Mbappe joining next season there is almost no doubt that they will become La Liga champions again next season. I think even Real Madrid can get a treble winner next season by winning the Copa Del Rey and the Champions League. Mbappe will take Real Madrid to a different level next season.
Anything is possible for Real Madrid next season because they gat all the best players in their team. I also expect to see them win treble next season, and if they don't it means that they did not take the advantage of their strength in those competitions.
Barcelona might still experience what happened to them this past season, in which they ended the season with no trophy. This is because Real Madrid added top class players to their team even after winning the champions league with players that Barcelona was unable to defeat. I pity for Barcelona as they are facing financial difficulties.
