Ancelotti confident Real Madrid are nearing their best
Jude Bellingham, Arda Guler and Kylian Mbappe were on target on Saturday, moving to within two points of LaLiga leaders Barcelona.
Since losing 4-0 to Barca at the end of October, Madrid have won four of their last five LaLiga matches, with their sole defeat coming against Athletic Bilbao on Wednesday.
But Ancelotti feels his team are rediscovering their best form.
"Bellingham has scored his fifth goal in a row. He's back and in good form. Mbappe scored too," he said.
"We have to hang in there, little by little we're coming back.
"We had to hold on at the beginning because Girona pushed hard. We did a good job collectively, and then we handled the advantage well. The team had more clarity and more ideas. I think the second half went very well."
The Italian also praised Guler's performance after the Turkish youngster scored Madrid's second goal.
"He wasn't good in the first half but in the second half he scored a fantastic goal," Ancelotti said.
"What I want to highlight is his work. He runs a lot and helps the team. His goal takes a bit of pressure off him.
"He's a young player with a lot of pressure around him and it's good for him to take a bit of pressure off."
An injury to Bellingham was a cause for concern for Madrid, but Ancelotti allayed any major fears.
"[Bellingham] is fine, he is available," said the Italian. "We've had the muscle injury to [Benjamin] Mendy but the rest of it is just knocks, nothing more,"
Mbappe's goal brought up his 200th in the top five leagues, while Bellingham has scored in five consecutive league games in a single season for the first time.
