Clement Lenglet has insisted that Barcelona players must accept the criticism that comes their way following a 0-0 draw with Slavia Prague in the Champions League.
Ernesto Valverde's men have come under pressure following a lukewarm display that culminated in the club's second goalless draw in four European games this season.
The stalemate at Camp Nou comes up against the backdrop of a surprise 3-1 defeat at the hands of Levante over the weekend.
When asked about the whistles that came at full time, Lenglet told AS: "People have the right to express themselves and we have to accept it. Now, we have to work."
Despite being top of La Liga, Barcelona are only three points ahead of seventh-placed Getafe and have already lost three times in the league since August.
Reports have strongly linked Ronald Koeman, currently in charge of the Netherlands national side, with becoming the club's next manager.
