David Bentley believes Sunday's clash at Chelsea can kick-start our season.
We've suffered 2-1 defeats in our opening games of the Barclays Premier League campaign against Middlesbrough and Sunderland.
Chelsea, meanwhile, are up and running with two wins out of two, the second a typically ground-out 1-0 victory at Wigan last weekend.
The Blues boast a formidable record at Stamford Bridge but David insists this type of test could bring the best out of us.
"It's great to test yourself against a side like Chelsea and I'm thoroughly looking forward to it," he said, ahead of his first derby clash in a Spurs shirt. "If we go there and put in a solid performance, play good football and get a positive result it could kick-start our season.
"Chelsea look good, they look solid. They have a way of playing, a direct style and they are strong but every team can be beaten. Look at us for example - I wouldn't have thought we'd lose our first two games.
"We're more than capable of beating them, it's just about performing on the day."
David was involved in just about everything as we tried to get the better of Sunderland last Saturday. He was denied twice by Craig Gordon and set-up chances for Gareth Bale, twice and Darren Bent, but it wasn't to be.
"It just didn't happen for us - that's football," he stated. "You can't win every game. You just hope this is our bad run and we'll come through it.
"There is nothing to be too disheartened about - it's been a tough start but it will be alright."
