Ledley King believes there is no time for us to dwell on two straight defeats with a trip to Chelsea next up for Juande Ramos' side.
The skipper admits the start to the season has been difficult to take, but is now focused on making amends in a London derby at Stamford Bridge.
Ledley believes plenty of hard work will be needed over the coming week in order to give ourselves a chance of repeating our heroic Carling Cup Final victory over the Blues next Sunday.
He said: "It's been a disappointing start but now we have to pick ourselves up because the next game is Chelsea, so we can't feel sorry for ourselves - we have to continue to work hard.
"Everyone knows Chelsea is a tough game and we've had many tough games against them, especially over the last couple of years.
"They've got off to a great start, but we've got to go there and give a good account of ourselves, so this week will be about lifting the spirits and getting the buzz back around the dressing room."
Ledley also took time to look back on Saturday's defeat at home to Sunderland, adding: "It's disappointing because we want to make White Hart Lane a fortress, so we didn't want to mark our first home game of the season with a defeat.
"It could have gone either way and I don't think they had many opportunities in the second half, but they put their chances away and, although we had a lot of possession, we couldn't seem to break them down.
"Our goal came at a good time with 15 or 20 minutes left, so our natural reaction was to push on and go for the winner and we got caught out."
