Messi fans demonstrate outside Camp Nou football stadium after he requested to leave Barcelona. Messi is Barca's record scorer and helped the club amass four Champions League titles, 10 La Liga titles and six Copa del Rey trophies. Barcelona's latest season, however, was not only devoid of trophies (for the first time since 2008), it was also defined by chaos and ended in humiliation with a 8-2 Champions League quarter-final defeat by eventual champions Bayern Munich.
