Spurs go to Stamford Bridge top of the Premier League and shaping up to be title contenders.
"Maybe we don't go there on top of the league," said Mourinho. "Maybe Liverpool gets a point or a victory at Brighton and then we don't go there top of the league.
"Going there top of the league or with Liverpool top doesn't change anything for us.
"We are always contenders to win the next match. Nothing more than that. We are going to be there, three possible results. We know anything can happen, but we go there and our objective is to win the game."
"I want to believe yes," said Mourinho when quizzed about their availability. "Little things, that if I wanted to push and if I wanted to risk a little bit, they could do it."
