According to Mundo Deportivo, Barcelona made comprehensive adjustments this summer around their Champions League campaign. Flick hopes stronger pressing, speed, experience and balance will allow the team to approach the Champions League, which begins tomorrow local time, in their best condition.

All of Barcelona's sporting decisions this summer were made and implemented with the Champions League, which begins tomorrow local time, as the focus. These decisions covered everything: signings, departures, tactical adjustments, and the positioning of new arrivals in terms of football ability and personal qualities. The only signing they failed to complete was Julian Alvarez, but based on current performances, he does not appear to be that important.
Flick hopes to complete the final upgrade and truly challenge for Europe's top trophies. In the past two seasons, the German coach led the team to dominate La Liga, but they were unable to maintain sufficient competitiveness in the Champions League. Flick has therefore concluded that the team needs stronger pressing, the ability to win the ball back near the opponent's penalty area, and faster progression into the next attacking phase. The team also needs to be more experienced when handling specific stages of matches and unexpected situations.
To improve pressing and speed, Barcelona brought in Gordon and Adeyemi; to add more match experience, the club signed Rodri, described as the world's best defensive midfielder. Real Madrid and Florentino Perez also played a role in helping this transfer happen.
Today's Barcelona have taken Flick's system characteristics to their highest level. The team has stronger pressing, more direct attacking play, greater threat, and more goals through the new attacking trio; Rodri's arrival has made the team more balanced and experienced.
Based on the current league-opening statistics, this is already the best Barcelona side under Flick's management. The team has collected 12 points from its first four matches, scored 17 goals and conceded only 2; at the same stage last season, the figures were 10 points, 13 goals and 3 goals conceded, while two years ago they had 12 points, 13 goals and 3 goals conceded.
Facing the Champions League, Flick is more prepared than ever before, and at present everything is in favor of the German coach and his team.
