Henry believes that coach Hansi Flick's tactics were a contributing factor in the loss. Specifically, he feels that the team's high defensive line was too vulnerable to attack.
According to Henry, when facing strong opponents, a high defensive line can leave the team exposed to counterattacks. This was evident in the match against PSG, where every move led to scoring opportunities.
Henry has been vocal about his concerns regarding the team's tactics for some time, but they did not seem to be taken into consideration by the coaching staff.
Henry's comments suggest that Barcelona needs to adapt and become more cautious in order to regain its position as a top competitor in European football.
