However, Conte has backed his players to perform against Sam Allardyce's in-form side as Chelsea look to move level on points with second-placed Manchester United.
The 48-year-old told reporters: "I have different options and I have another day to make the best decision for the game. Every single player is in good form and I have another day to make the decision.
"It's an important game for us. It's the last game before Christmas and I would like to celebrate with a good win. It will be very important to get three points.
"They have won four from the past five games and they're in good form. They've changed the coach and they're having good results. We must pay great attention on Saturday."
Chelsea warmed up for the fixture with a 2-1 victory over Bournemouth in the EFL Cup quarter-finals on Wednesday.
