Barcelona's title hopes are officially over after they were beaten 2-1 by Celta Vigo at Camp Nou on Sunday.
Santi Mina struck twice to cancel out Lionel Messi's opener as Barca's bid farewell to Camp Nou for the season with a whimper.
Messi headed in the opener but Barca were made to pay for their wastefulness when Mina scored with Celta's first attack of the first half.
Barca weren't as good after the break but still had control of the game until Clement Lenglet was sent off for two bookings.
Even then, substitute Martin Braithwaite wasted a golden chance to win it for Barca before Celta stole the points in the 89th minute.
Luck smiled on the visitors when a poor cross bounced back off the woodwork and Mina was on hand to score his second.
It brought the curtain down on Barca's faint title hopes with one game to go.
A run of one win in five games has proved costly for Ronald Koeman's side at the decisive phase of the season.
Atletico's late win against Osasuna and Real Madrid's victory at Athletic Club means Barça are confined to third for this season.
