Lalliga league will soon start,and a lot of clubs have prepared adequately to face the new season.Barcelona will have a lot of work to do if they will be able to compete with Real Madrid this season because with the kind of force Madrid have,I don't think Barca will be able to match their energy.Madrid got Mbape in a free transfer,and ever since he made the move,he has shown to Madrid fans that he is worth every Money they are paying.
He has already scored goals in their pre season game already,and he will be hoping to win the golden boot this season.
Barcelona are aiming to sign Dani Almo and Nico Williams so they can add to their squad for next season.If these deals materialises,then I'm quite sure Barça may either win the league or win the champions league.
Yes, several teams are starting to prepare their strengths as best as possible by recruiting players who are ready to bring big changes this season. But look at Girona, they actually sold their mainstay player, Dovbyk, to As Roma, even though Dovbyk was their top scorer and was their goal machine last season.
If you look at the ins and outs of Girona, of course the biggest shareholder is CFG, so their finances are of course quite strong, but unfortunately they to sell their star players in this transfer market.
So, for Barcelona they continue to try to get Nico Williams and also Dani Olmo where management continues to make contact with both teams to complete this transfer. I think your assumption is too high because to win the UCL trophy you definitely need quite strong strength and I think Barcelona will find it difficult to do it this season.
