Gomes suffered a horrific fracture dislocation to his ankle on November 3 but has been passed fit for Sunday's game at the Emirates after completing 60 minutes of a behind-closed-doors friendly last weekend and training this week.
"Andre is available to play," Ancelotti told a pre-match press conference. "He has trained well, properly, with confidence, without problems and in my opinion he is ready to play.
"Before the game we are going to talk together and decide if he can start the game or if he goes on the bench."
Asked if Gomes needed to recovery mentally as well as physically, Ancelotti added: "This is personal, really personal. It's really important for me to talk with him.
"What I saw in training he was totally confident, without problem, he was not worried to have contact with team-mates but I think it's really important to talk with him. If he's confident, in my opinion he can play without problem."
