Stevenage chairman Phil Wallace has said his side have the belief to cause an FA Cup shock against Tottenham.
Boro were drawn against the Premier League giants in the fifth round after a 1-0 win over Notts County.
And Wallace has issued a warning to those who may doubt his club's conviction to reach the quarter-finals.
"I think they might be wrong because we'll be really focused and believing we can get through to the next stage," he told BBC Three Counties Radio.
"We're just focused on trying to get through to the last eight.
"We're in the last 16 in the country after an incredible performance."
The League One side have already caused one FA Cup upset this term, overcoming Championship Reading 1-0 in the third round.
And they have recent experience of dumping out a top-flight outfit, beating Newcastle 3-1 in last season's third round.
But Wallace, whose team were in the Blue Square Bet Premier two years ago and are now in the top six of League One, has stressed the importance of putting the FA Cup clash to one side until Spurs come to Broadhall Way on the weekend of 18 February.
"I'm sure the players will be thinking about Spurs about three or four days before the game," he said.
"We've got four very important league games before then, we're in a play-off position and we want to get promoted to the Championship."
Looking back at the victory over the Magpies, the Boro chairman reserved praise for boss Gary Smith, who took charge of the side for the first time since replacing Graham Westley.
"I don't think you could write the script if you wanted," said Wallace.
"I was so pleased for him. It was a brave decision to come in because a win was fantastic but, if he had lost in his first game, with it being so important, it would have been very difficult.
"I'm pleased for Gary and his assistant Mark Newson and so delighted for the club as a whole."
