Real Madrid are prepared to fight on until the end in their La Liga title defence this season.
Los Blancos held on to secure a vital 3-2 La Liga win over Celta Vigo on May 4, which keeps the defending Spanish champions four points behind leaders Barcelona, with four games left to play.
Hansi Flick's team have the clear advantage, but Ancelotti can ramp up the pressure, if his side win away in Catalonia on May 11.
Victory on the road against La Blaugrana would tighten the gap to a single point for the three-game finale and amp up the tension on Flick's treble chasers this month.
Turkey international Arda Guler netted the opening goal for Ancelotti's side before laying on an assist for Kylian Mbappe's winner.
The 20-year-old has burst to prominence in recent weeks, despite playing a back up role for the majority of the campaign, and Ancelotti is delighted with his turnaround.

Three goals and four assists in La Liga action is a low-key overall tally, but goals in back-to-back matches have secured key points for Real Madrid, ahead of that all-important trip to Catalonia.
Ancelotti has hinted Guler will play a greater role next season - albeit likely to be under a new manager - and the Italian believes his firmness with the player and his agent at the start of 2025 is paying off.
"His progression is natural. The Guler of September is not the Guler of today. He's changed a lot physically, due to his hard work and effort," as per reports from Marca.
"I have the responsibility of managing what's best for the squad, not just for one player. That affects some more than others.

"Here you have to sit on the bench to become a starter. He'll do better next year. He has the profile to be a starter.
"He hasn't taken to the bench well, but he also hasn't handled it badly. Two months ago I hit out at the people around him - but now I have to congratulate them."
Ancelotti faces a key call on whether to start Guler in the season-defining game at Barcelona, with Rodrygo Goes facing a fitness battle, but he will be the first to be thrown in, if the Brazilian misses out.
