''We have spoken and we will take the decision together after the Everton game to see if he needs to rest two days or if he wants to stay here and play against Cardiff,'' said Ancelotti.
''He has not asked for any time off to see his wife. My preference is what he wants. I am totally supportive of him. We will make the decision together.
"We want to respect the FA Cup because it is an important trophy in this country so we will speak after the game against Everton and make the decision, the right one for us both.
"The FA Cup and John's marriage are different; FA Cup is professional, the other thing is private."
On the pitch Ancelotti is hoping Chelsea's defending will mot be as sloppy as it was in their last meeting with Everton.
The Toffees drew 3-3 at Stamford Bridge in December when some of Chelsea's set-piece defending was inept to say the least.
But Ancelotti believes tomorrow's clash with Everton and Manchester United's game against Aston Villa could, if results go his way, prove to be a turning point in the season.
"The Everton game at home was strange because we conceded three goals from set pieces, but we played very well,'' Ancelotti said.
"Tomorrow will be a different game but we need to win. We need to maintain our position at the top of the league but it will not be easy."
Meanwhile, Ancelotti refused to be drawn into a war of words with Arsenal following their victory over the north Londoners on Sunday.
Arsène Wenger moved to put the record straight after Chelsea midfielder Michael Ballack told the Arsenal manager to stop looking for excuses in the wake of their 2-0 defeat at Stamford Bridge.
The defeat left Wenger's team nine points off the Barclays Premier League leaders and, while Wenger congratulated Chelsea on their efficiency, he also claimed ''we didn't get a demonstration of football''.
Ballack responded by taunting Arsenal's inability to win big matches and to vary their tactics, declaring: ''It is always the same style. If you play tactics like we did, you can beat them.''
But Ancelotti said: "Ballack explained his position about the game. Ballack said good things and we prepared very well and we did what we wanted on the pitch and nothing else.
"I heard what Wenger said about our performance on the pitch but we did the same as Arsenal.
"We had a very good performance. Usually we are in control of the game with possession but it's difficult to keep control of the game without possession, so tactically we did very well."
