The Toffees and Palace are two of five teams who have won both their opening matches so far, with Ancelotti's side impressively defeating Tottenham 1-0 away before putting five past West Brom at Goodison Park.
In the first two fixtures of the Premier League season, the Italian boss named an unchanged side, and expect that to be the case here as he looks to keep the positive momentum going.
Allan, Abdoulaye Doucoure, Andre Gomes, and James Rodriguez should return to the starting XI against Palace after being rested from the line-up versus Fleetwood.
Yerry Mina and Michael Keane are the only two fit senior centre-backs at the clubs so they will start while Mason Holgate recovers from injury.
Jarrad Branthwaite, Cenk Tosun, and Jean-Philippe Gbamin are out also.
