Fifth-placed Spurs twice came from behind to draw 2-2 at Stamford Bridge, but their fate is no longer in their own hands ahead of matches with Stoke and Sunderland.
"The destiny's not in our hands any more," the Portuguese said.
"What we have to do is what we had to do also, to win the next fixtures and hopefully see if somebody can slip up and change our position.
"Hopefully if we're able to take this to the last game of the season, when we play at home [against Sunderland], and Arsenal go to Newcastle and Chelsea play Everton, anything can happen. It's unpredictable."
