One specific feature of Barcelona’s 1-0 loss to Real Sociedad on Sunday was said to be enough to “drive Hansi Flick crazy.”

The manner Barcelona began both halves of the match, according to Mundo Deportivo, was more significant than the contentious decision to disallow Robert Lewandowski’s goal.

According to the article, the German coach is extremely unhappy with his team’s “cold” start and missed opportunities.

Sheraldo Becker had a chance immediately after halftime, but Real Sociedad had to be denied an early lead at the beginning of the game by a last-ditch challenge from Marc Casado.

The Barca players are accused of entering the match with a “moral superiority”—possibly anticipating victory—which is “something that drives the German coach crazy,” and his staff is well aware of his frustration.

Flick will undoubtedly make his players aware of this and want to see it put to the test when Barca resumes play following the international break.
