Crucially, Barca' players never lost faith in Flick's fearless brand of football. He asked them to play an incredibly high line, which is usually a terrifying prospect for defenders, but Barca's back four relished the challenge. There were times when it looked like a flawed approach, particularly during what Flick called a "sh*tty November", when the Blaugrana threw away the early lead they'd built up in La Liga by dropping eight points in three games.
However, the ex-Germany boss was adamant that the risk would eventually prove worth the reward - and he was spot on in that regard. Madrid tried four times in three different competitions to take full advantage of Barca's adventurous approach - but not once did they manage to get the better of the Blaugrana, who haven't lost in the league since December.
Of course, he was fortunate to have a tremendously talented group of young players willing to follow his every command. As Laporta predicted, having access to the most famous academy in world football was of great help to Flick given the lack of new arrivals last summer.
Marc Casado, Fermin Lopez and even the injury-hit Gavi have all started at least 10 league games this season, while Alejandro Balde and the fantastic Pau Cubarsi have been regulars in defence. Lamine Yamal, though, is obviously the jewel of La Masia, the most talented teenager the game has ever seen.
Yamal is capable of doing incredible things with a football, but what really marks him out as a generational talent is that he's capable of doing them at the most important moments in the most important games, like the massive come-from-behind win over Atletico Madrid at the Metropolitano on March 16 and Thursday's title-securing win over Espanyol.
"To be a difference-maker at such a young age is really incredible," Flick quite correctly stated. "Having him is key for us not only because of his quality, but he also presses high very well. He combines talent and pressure and that's massive for us. He is outstanding."
Of course, Yamal - who has a league-high 12 assists this season - is just one part of the most formidable forward lines in world football.
