The two teams will meet in the final Jornada nan determine the next Sunday after both drew this weekend, Atleti at home to Malaga (1-1) and El Barca in home visits Elche (0-0).
Atletico currently still holds a three-point advantage over the Catalans, but they certainly have to give up that title to his knees in the Camp Nou.
"Peeve when you give all that is required in the game [but failed to win it], because the players have deployed everything," said Simeone after failing to reap the maximum points counter Malaga.
"Now there is a 50-50 chance, like in any final action. History Atletico immortal. Sunday will be vital for the club."
"I do not have an opinion about our rivals.'s Not easy to win and at the end of a long season like this might happen. I played for 20 years and I understand what happened," said El Cholo.
Atletico Madrid boss Diego Simeone, calling his men together have a strong chance to Barcelona to win the Spanish Primera Division this season.
