Karen Hills is looking for Spurs Ladies to show their collective character as they go through their toughest spell yet since promotion.
Sunday's narrow 1-0 defeat against QPR represented their fourth loss in a row in the FA Women's Premier League South.
That run has dented their excellent start to the campaign at this higher level after promotion last season.
Chances were few and far between in the first half against QPR but the visitors scored what turned out to be the winning goal in the 35th minute when Cherrelle Albert found herself unmarked from a free-kick and converted.
Karen changed things around at half-time with Sam Pittuck pushed forward from defence.
The team slowly got on top and carved out three chances to equalise in the final 10 minutes.
Substitute Chelsea Golding hit the crossbar and was then denied by QPR's keeper and finally Emma Kayser sent Sam Pittuck clear only for the goalkeeper to come out on top again.
"We were really disappointed not to come away with a point," said Karen. "I thought we deserved to get something from the game.
"We're not getting the rub of the green at the moment which frustrating for everyone.
"Having said that, we cannot afford to give away cheap goals and ultimately, that lack of concentration at a set-piece cost us.
"The next couple of weeks is going to be a good test of the girls' character and we will be working hard on the training ground to get our season back on track."
That starts with a trip to Gillingham this Sunday.
