Spurs want victory against Chelsea at Stamford Bridge tonight to keep their top-four dream alive and make up for that heartache 12 months ago.
It is in their own hands provided they beat the Blues, Stoke and Sunderland in their last three games.
And Tottenham winger Bale told The Sun: "I think I was more annoyed than anything else watching that Champions League final and seeing all our hard work wasted.
"I thought Bayern battered Chelsea but it was one of those nights which you couldn't control. What happened has driven us on and we've used that as an incentive this year.
"If we win all our games there's nothing which can stop us qualifying, so it's up to us.
"We've had a taste of the Champions League before and I know how much everyone wants it.
"We need to keep our focus on what needs to be done and finish the job off."
