Barcelona manager Hansi Flick plays with an interesting tactical system.

Flick sets his team up to play a high defensive line, and so far it has been effective.

According to reports from MD, Hansi Flick urged his players to stick to their game plan and maintain a high defensive line against Real Madrid, which helped Barca win.

Hansi Flick even warned that he’d sub off anyone who failed to follow his tactics.

“Anyone who drops back a meter, I’ll substitute them,” he warned.

Flick also made a notable change by introducing Frenkie de Jong for Fermin Lopez at half-time.

Barcelona had more control of the midfield, and that was the goal of the substitution.

“The idea was to seek more control,” Flick stated after the match.

Barcelona beat Real Madrid 4-0 away at the Santiago Bernabeu to create a sixp points gap over their bitter rivals.
