Nacho Fernandez's second-half goal ensured Real Madrid still have a chance of retaining their LaLiga title on the final day of the season as they beat Athletic Club 1-0, but Atletico Madrid remain in the driving seat.
Madrid briefly looked to be going into their last match of 2020-21 at the top of the table after Nacho fortuitously put them in front while Atletico trailed, but Diego Simeone's men enjoyed a late turnaround against Osasuna to stay two points clear.
The build-up to Madrid's trip to San Mames had centred around reports Zinedine Zidane will leave at the end of the season, and for much of the game his team looked incapable of clinching the victory that could set up a triumphant conclusion for the French coach.
But with 22 minutes to go, Nacho bundled home what proved to be the winner, though Atletico's battling comeback at the Wanda Metropolitano means Madrid will need a helping hand if they are to be champions again, while Barcelona's chances are over following a 2-1 home defeat by Celta Vigo.
