The Barcelona trainer has insisted that he has no reason to be worried about the Argentine after the forward failed to get on the scoresheet in the Blaugrana's last two games
The Argentine was unable to find the back of the net in the 1-0 loss against the Blues last week and in the 2-1 Clasico loss to Real Madrid in La Liga on Saturday.
Despite the mini drought, Guardiola feels there is no reason to worry ahead of Tuesday's return.
"I never allow myself to be concerned about Messi. Not even if he doesn’t score for 27 matches," Guardiola stated at a press conference.
"I give him tranquillity and the right to not have to score goals until he wants to. He’s scored a brutal amount of goals this season.
"Let him play, be happy and be who he’s always been. His ambition helps us all."
The match at Camp Nou kicks off at 20.45CET.
