Younes Kaboul is wary of end of season tragedy as fourth position in the Premier League has turned into a slippery surface for Tottenham.
"If we lose next weekend, it's going to be a big disappointment. It's important for us, so we have to take all three points in the last game, definitely," the defender told reporters.
Spurs currently lie fourth in the table, with one game left to play, but with Newcastle trailing them in fifth by just one point, their final standing is far from certain.
If the north London club lose against Fulham at home, the Magpies could overtake them with victory away at Everton.
Alternatively, Harry Redknapp's men could still manage to steal third place from bitter rivals Arsenal, if the Gunners fail to beat West Brom at The Hawthorns.
Even if Kaboul and his company manage to keep the last seat for Champions League qualification, they'll have to wait until the final whistle of this year's European final between Chelsea and Bayern Munich to find out their luck.
A win for the Blues will send Tottenham into the Europa League, and all of their efforts will go to waste.
Martin Jol returns to White Hart Lane as the Cottagers' manager, and the Spurs defender hopes that their former boss will not shatter their European dreams.
"If we don't get into the Champions League, it's going to be very disappointing for us because I think we've had a very good season.
"I think we deserve the Champions League. We don't want Martin to come back and get a result. No definitely not!"
Tottenham threw away a 10-point lead they held over Arsenal, due to a series of bad performances. But, Kaboul reserved praised for his teammates after they managed to regroup and reignite their Champions League hopes.
"I think in the last three games we've shown quality football and a very good team spirit," he concluded. "That's the most important thing in a football team.
"In the squad you need to have a very good team spirit and everyone going the same way."
