Spurs take on Camden Town Ladies in the semi-final of the Capital Cup* at Cheshunt FC (2pm).
Still alive in all four cup competitions, the team has already reached the Ryman Cup Final and will face old rivals Charlton at Cheshunt on Thursday, April 14.
It could be the same final line-up in the Capital Cup as Charlton meet QPR in the second semi-final.
Camden Town play in the Premier Division of the London & South East Regional League but manager Karen Hills knows her players won't get sucked into any sense of taking Sunday's tie for granted.
"We're on a good run and all we're really thinking about continuing that momentum," said Karen.
"Any cup tie can be a stumbling block so we'll go into it with the right mentality and try to get the job done. I'm sure Camden will be ready to give absolutely everything but it's about how we perform."
The ladies had a rare outing in the FA Women's Premier League last weekend and produced a convincing 3-0 win against Plymouth.
They now take on Camden before a big one in the fourth round of the Women's FA Cup against Women's Super League 2 side Aston Villa at Cheshunt on Sunday week (February 28, 2pm).
*The Capital Cup is run by three FA's - London, Middlesex and the AFA.
