Ancelotti was drafted in on a four-and-a-half-year contract last December to replace Marco Silva, who failed to churn out the desired results in Merseyside.
The Toffees were sitting in 16th place and only three points above the drop zone when the former Chelsea boss was appointed.
Ancelotti has breathed new life into Everton as they now sit just six points behind sixth-placed Wolverhampton Wanderers, who are vying for a Europa League spot, should the current season resume.
Digne believes appointing Ancelotti was the right decision and Everton can even aim to play in the Champions League in the future.
"We are building a very good project," the defender told Sky Sports News.
"We can do something very special and very good.”
"We can do better than last year (8th) and maybe finish in Europe this year.”
"We have something special at Goodison Park. We have the fans, they are behind us every time, everywhere.”
"We have something special in the club because we are a big family and if we can transform results on the pitch, it would be amazing.”
"Everybody is giving their best and we will see what happens.”
"We have to keep this mentality and to do our best every time and I am sure we will finish very high."
The Frenchman added: "We are building something, we are building a project. We have very good players.”
"In a few years, they have bought a lot of players, they have invested a lot.”
"We have to finish in the top four, top five, and to play the Champions League."
