Lamine Yamal and Ferran Torres scored two goals each, while Robert Lewandowski, Andreas Christensen, and Gavi also found the back of the net.
Flick commented after the match, saying his team had a good start but struggled in the first half before finding their rhythm in the second.
He praised Gavi, who played well in both defensive and midfield roles, and expressed satisfaction with the overall performance, especially considering the team's focus on player care and injury prevention.
Flick noted that each player received 45 minutes of playing time, with special attention given to Eric and Iñigo, who were experiencing discomfort.
