Ahead of a return to action on Saturday lunchtime at Chelsea, Mourinho feels that Spurs are "in trouble" with the team struggling with a number of fitness issues.
Speaking to BT Sport, the Portuguese said: "I'm not worried with the 1-0 - we can go there and win. What worries me is that these are our players for the next however many matches.
"[Lucas] Moura was absolutely dead, [Steven] Bergwijn was absolutely dead, [Giovani] Lo Celso was absolutely dead. We are really in trouble. If it was just this game I'd say 'no problem' but we have FA Cup and Premier League games.
"I know [Erik] Lamela could only give us 20 minutes and I knew [Tanguy] Ndombele could not play for 90 minutes. I tried to manage the pieces I had."
While Spurs have an eight-day break after the Chelsea fixture, they play five games in two weeks from March 1. body check tags ::
