The League One Lions come to White Hart Lane on a lengthy unbeaten run and having dispatched three top-flight sides from the competition already this season – Bournemouth, Watford and Leicester City.
Plaudits have been rolling in for both clubs ahead of the tie, with Harris named the top boss in the third tier of English football for February, while our talismanic front man Harry Kane – himself a former Millwall loanee – picked up the EA SPORTS Player of the Month prize for the same period in the Premier League.
But with a fresh test coming on Sunday, Harris has cranked up the pressure, insisting his team has nothing to lose.
“I'm looking forward to it. The test in front of us speaks for itself – it's a huge fixture,” said the 39-year-old former striker, who had two separate spells at Millwall as a player.
“Not only are we playing in an FA Cup quarter-final, the best club competition in the world, but we are also going to Tottenham Hotspur, who are a really talented side. We've earned the right to pit ourselves against one of the best in the country. We've got nothing to lose and everything to gain.
“The pressure is on Tottenham. They've got 30,000 people turning up expecting them to beat League One Millwall.
“Spurs have taken the cup seriously. Mauricio Pochettino wants to win the trophy and the fan base demands it. At this stage of the competition, you want to play the best players and the best teams.”
