Hansi Flick is absolutely right; he's doing his job well, making Barcelona's game stronger. I've noticed that there's no selfishness among the players, resulting in good, accurate passes. The players' confidence has also improved since being coached by Hansi Flick.
It was unexpected that Hansi Flick would bring such success in the first season. Because after Mbappe joined the squad, the Madrid squad became very strong. But even then, Flick did not care about Real Madrid at all. He was able to create a very strong bonding between the Barcelona players. As a result, the team became the La Liga and Copa del Rey champions. Barcelona won all four matches against Madrid by a large margin. Barcelona ended a great season even though they could not win the Champions League title.
This season too, Flick did not make any changes to his squad. He only added Rashford to the squad. Since the squad is unchanged, the bonding between the Barcelona players is also strong. So it can be expected that we will see good performance from Barcelona this season too.
