Ronald Koeman is "convinced" that four wins will lead to the La Liga title for Barcelona as they prepare to host league leaders Atletico Madrid on Saturday.
A win will take Barça ahead of Atletico at the top of the table, with games against Levante, Celta Vigo and Eibar to close the campaign.
However, four wins won't be enough for Barça if Real Madrid also win out. Los Blancos are level on points with Barça but have the head-to-head advantage.
"I haven't changed my mind. I am convinced that if we win our last four games, we will be champions," Koeman said in a press conference on Friday.
"We have recovered a lot of ground in terms of points to be where we are, something we didn't expect 3, 4 months ago to be able to fight for the title.
"Atletico is one of our last four games. I understand games this weekend could see one team or another take a step forward, but we have to be aggressive without the ball, we're convinced we're going to play well."
