I am confident that Barcelona will change their strategy next season and perform well and win the title because Barcelona is a strong team in the laliga, it is just that they did not have better players to help them do well and win the trophy last season however, next season Barcelona will do everything necessary to make them do well because they have a new coach in the team; he will try his hardest to win the title with Barcelona.
Barcelona always did their hardest effort in each season, dude. Sure, the lack of quality players became the biggest problem for Barcelona. Even Xavi was the coach of Barcelona, he couldn't win any trophy because he has no proper squad in the last season. Actually, we can understand if Barcelona failed to win any trophy. Well, the new coach means to have a new strategy. It is very possible that Barcelona to change their strategy but I don't see it will be effective to improve their performance as long as they still have the same squad. Hansi Flick is a German coach, he probably has own strategy and different play stayle. Honestly, I doubt if Barcelona players will easily adapt with Hansi Flick.
And all I want of Barcelona is that they strive to sign new players because the team would never improve without them since players come first after coaches. Now that they have a new coach, the president should release funds to get better player to the team.
Laporta has no money to buy any player. Barcelona needs to sell their valuable players if they want to have money for buying new players. I heard that Barcelona is ready to sell Lewandowski but I doubt they will get a proper striker to replace him. Selling players is not a bad choice although I think it is too risky for Barcelona. Instead of improving their squad, it may lower their squad quality if they can't get proper replacements.
