The long trip to Wales once again proved the team's undoing as Cardiff raced into a 3-0 lead before running out 4-0 winners in the FA Women's Premier League South.
This Sunday's scheduled fixture against Brighton has been postponed, so the team have arranged the friendly against the Hornets at the Frederick Knights Sports Ground, Tottenham, kicking-off at 12noon.
"Hopefully the friendly will encourage the girls to play with a bit more freedom as there is no pressure playing for points," said Karen.
"We would have liked to have played Brighton but it might just work in our favour as we've picked up a couple of injuries to Jenna Schillaci and Kim Lane, key players for us."
Back to chances and the team had chances after Sarah Wiltshire opened the scoring on the half-hour, most notably when home goalkeeper Sophie Dando denied Jenna from Andra Marcoci's cross.
However, Cardiff struck twice before half-time through Bethany Lloyd and an own goal and at 3-0 down, it was an uphill task.
Dee Smith and Shannon Maloney entered the fray for the second half and Spurs responded with good possession as Rosie Kmita had a goal disallowed.
Jenna had to depart injured 15 minutes from time and Lloyd hit the fourth for Cardiff late on.
Assistant Manager, Juan Amaros, reported: "We didn't turn up for the first half. Perhaps we paid the price for travelling at 7am, but that can be no excuse. You have to be at 100 per cent for 90 minutes, and we only managed it for 45.
"Having said that, I'm sure we'll learn from this and come back stronger."
Spurs Ladies v Cardiff: Morgan, O'Halloran (Smith, 46), Schillaci (Woodgate, 75), Lane, Grafton, M Kmita (Maloney, 46), Kmita, Cooper, Wynne, Martin, Marcoci.
