Luis Suarez showed "phenomenal" strength to recover from biting bans to become a Barcelona star, according to former Liverpool team-mate Charlie Adam.
Suarez has won 13 major trophies with Barca since moving from Liverpool in 2014, including the treble of La Liga, the Copa del Rey and the Champions League in his first season in Spain.
The Uruguay star secured a switch to Camp Nou after a stunning campaign in the Premier League in 2013-14, in which he scored 31 goals in 33 league games to win the European Golden Shoe and be crowned the PFA Players' Player of the Year and the Premier League Player of the Season.
