The Blaugrana's performances are concerning the French tactician, who believes their superstar is too often asked to shoulder the burden
Barcelona rely too heavily on Lionel Messi and are playing 'like a team in crisis', according to former Arsenal boss Arsene Wenger.
The Liga title-holders struggled to a 0-0 Champions League draw against Czech side Slavia Prague at the Camp Nou on Tuesday night, having lost 3-1 to Levante in the league on the weekend.
Wenger believes that despite leading their two main competitions, Barca aren't gelling together as a team and were just waiting for their superstar Messi to create a moment of brilliance.
