Pedri was just as integral to Xavi as he has been to Flick. However, the Spanish international struggled to remain fit. During Xavi's two years and eight months of reign as Barca's head coach, Pedri was out of action for as many as 386 days, and missed over 70 games for club and country.
Things have been different under Flick as Pedri seems to have put his fitness problems past him. In September, he spoke about the fitness work that he undergoes as part of Flick's training methods and his comments were perceived as an indirect jab at Xavi.
"Yes, I feel liberated," Pedri told Mundo Deportivo in September. "I think Flick has also conveyed that to me, to play without pressure, to do what I know how to do and I feel much more relaxed. Physically, I can also see that I am much better at being able to do different things. Flick is very good at that, giving us confidence.
"We are working much harder at the club than before. I think the physical trainers who have come in are doing us a lot of good. We work very hard and that shows in the game. The team doesn't let up after the 70th or 80th minute, but rather maintains its physical level.
"We [the Spain internationals] arrived late [after the European Championship], but speaking with those at preseason from the start, they were really put through it. A lot of strength work, a lot of physical exercises."
