“Messi had suffered a series of grave muscular injuries, especially in February and march of 2006 that kept him from the Paris CL final, but also in December of 2007 and March of 2009 […] so when Guardiola came to the first team, there was an extensive plan of prevention and health care for Messi. Food, hydration and fixed rest were joined to a thorough preventive work. Juanjo Brau became his shadow, not only in Barça but in any trip with his NT. Each day Messi works during 45 minutes before training, and 30 minutes after, moving articulations, relaxing muscular tension, and working his lower limbs. People in the dressing room stress the importance of Messi’s dedication in the taking care of his own body. What was a serious problem, had become a procedure, taking in consideration a lot of daily effort.
It is also important to note the evolutionary process as a player. What in 2005 and 2006 [Messi] was a winger who ran 90 minutes at full speed, maybe in offensive plays, or maybe in keeping track defensively, has changed -– by explicit decision from Guardiola -– to an attacker that runs lightly and even walks for a lot of minutes, placing himself in central positions as a starting point, with short length associations with Xavi and co.; and that reserves his well-known accelerations and change-of-pace dribbles a few times per game: the chosen ones. That wild, intense Messi during an hour and a half, only gives himself away on the necessary moments: he has learned to choose those moments. This measurement from the technical staff show a significant decrease in explosive physical efforts that the player does per game. As a result, his muscular fatigue has been limited exponentially and now he is capable of facing 60 games per season, with reduced injury risk, contrary to the situation 5 years ago. As a matter of fact, and in the merging of trauma injuries and knocks in the game, only an overload in the “recto interno” in August of 2009 and an elongation in the “abductor” on November of the same year, has been accounted as muscular injuries for Messi, in these 3 and a half seasons with Guardiola.”
