Harry Redknapp has warned North London rivals Arsenal that his Tottenham side will fight all the way for third place in the Premier League.
A battling 0-0 draw at Stamford Bridge saw fourth-placed Spurs maintain their five-point lead over Chelsea in the race for a Champions League spot.
But they are now three points behind Arsenal, having been 10 points ahead as recently as last month.
"It's in our favour, Arsenal have got some tough games," insisted Redknapp.
"They've got Man City at home, Chelsea at home. It's all to play for still.
"We found ourselves suddenly from being 10 points clear to being behind Arsenal now.
"It can all change. We've got to keep picking up results."
Redknapp has challenged Tottenham to win six of their last eight Premier League games to at least secure a top-four spot and ensure a return to the Champions League next season.
"We've got decent games, I think," added the 65-year-old.
"We've got to make sure now that we win six out of the last eight, if we can. You'd like to think we've got a chance of that."
Chelsea caretaker boss Roberto di Matteo admitted his side might need to win all their remaining matches to overhaul Spurs.
The Italian said: "To make the gap up, we would have to win all of them.
"It's going to be difficult but, from the day I was appointed, we always knew it was going to be a difficult task.
"There are still eight games to play and we will try to win as many as we can to try to get into fourth spot."
Di Matteo was also unhappy that his side failed to get a penalty after Ramires went down in a collision with Spurs defender Benoit Assou-Ekotto.
"Assou-Ekotto just pulled him down because he wasn't aware of him. I think Ramires would've got on to the ball," said the 41-year-old.
"It wasn't a doubtful one - that was an absolute penalty."
