Matt Le Tissier believes Tottenham will "keep Chelsea on their toes" in the race for the Premier League title.
Spurs are seven points behind their London rivals with eight games to go after a remarkable 3-1 fightback against Swansea on Wednesday.
They were Leicester's closest title challengers last season until a significant dip in form at the end of the season cost them second spot.
But Sky Sports pundit Le Tissier is confident that this year Mauricio Pochettino's side will continue to push Chelsea all the way as the season draws to a climax.
"Spurs are making sure that they keep Chelsea on their toes," Le Tissier told Premier League Daily on Sky Sports News HQ.
"They had a lot of criticism at the back end of last season because they kind of petered out a little bit, but I thought 1-0 down, two minutes to go... to finish that game 3-1, I thought that showed what Tottenham are about this season.
"And I thought that was great character last night from Spurs."
The North London club will be looking to extend their five-game winning run in the top flight when they host Watford, live on Sky Sports 1 HD on Saturday, to keep the pressure on the current leaders.
Speaking on Premier League Daily, Alan McInally echoed Le Tissier's thoughts on Tottenham's title credentials.
"I've said for the last two months, I think they're going to be the biggest opposition," he said.
"I think they're the most powerful team in the league - they're a big team."
Tottenham's remaining fixtures see them go head-to-head with top four rivals Arsenal and Manchester United.
Yet McInally is convinced that Spurs - who are unbeaten in the league since February 11 - can avoid defeat for the remainder of the season.
"Spurs have had a great season - they're an absolute banker to finish top four," he said.
"I suppose a lot of the Spurs fans will be thinking 'well, we're going to finish above Arsenal' for the first time in however many years it is - that certainly looks like the case.
"It wouldn't surprise me if they go undefeated all the way to the end of the season."
