Real Madrid coach Carlo Ancelotti was disappointed after his side dropped two points in the race for the Primera Division title with a 2-2 draw at home to Valencia on Sunday.
Cristiano Ronaldo's stoppage-time goal salvaged a point for Real as they followed Barcelona and Atletico Madrid in failing to collect maximum points on a dramatic weekend in the title race.
Barcelona's draw and Atletico Madrid's defeat left the door wide open for Madrid but they struggled to push through it as the top three all dropped points on the same weekend for the first time this season.
Defeat for Madrid would have left the title in Barcelona's hands - they take on Atletico on the last day of the season - but the draw leaves it too close to call with leaders Atletico holding a three-point gap over Barca with Real two points further behind but with a game in hand over the top two.
Ancelotti told his club's official website: "We missed a good opportunity, but it's not the end of the world. By winning today, Atletico would have needed a win in Barcelona but now a draw would be enough for them.
"Cristiano's goal was very important. Losing today would have meant losing La Liga. Now we're still in the fight. It was a crucial goal".
Real reached the Champions League final last week with victory over Bayern Munich and Ancelotti stressed his side will also fight for the league title "until the end".
He added: "La Liga is a tough division, as it always has been. It will be decided in the last few games, like I've always said.
"It has been a tough matchday for all three teams at the top of the league and now the championship is more open than ever.
"The players weren't happy at the end because we went out to win. But we are still as motivated and eager as ever to continue fighting for the La Liga title until the end of the season.
"There are three games remaining and in order to have a chance of lifting the title we have to win all of them. It won't be easy, we have two away games, but we will fight tooth and nail to win them."
