Just six points separate the sides in the Barclays FA WSL - and Blues have a game in hand.
With a trip to Bristol City to come on Sunday, these next few days could have a defining impact on Blues, who sit 10th in the table.
The squad has knuckled down and refocused on their training ground since the last match, the heavy defeat the hands of Chelsea on home soil.
Marta Tejedor said that Blues have come together, showing the right mindset, in the past 10 days.
"We have been doing what we normally do, basically," said the Manager. "But we have focused a lot on understanding that if we want to get better, then we need to work better. If we want to get out of this situation and we trust ourselves, and have belief in the team, that's what we have to do.
"Instead of getting disappointed and not being willing to work, we have to do the opposite. It is encouraging the girls, one another, to do the best you can do and maintain that mindset that if we work well, then something good will come."
Bristol City got thumped by a WSL record 11-1 at Arsenal on Saturday, which dropped them a position below Blues in the standings due to goal difference.
Tejedor acknowledged: "This week can make a big difference. If it is perfect and we get every point we are playing for, it will put us in a much better situation in the table. If it doesn't work, then it will hurt us a lot."
Spurs have tended to be very much boom or bust this season, having yet to draw in the league.
"We have analysed some matches of theirs. We have seen quite big differences in the system and the way they play. And then as well some common things.
"I am convinced that we can win the game. As always in football anything can happen. But I know if we can be on our competitive level, it should be an open match and we can get the result. If we do, it will help us a lot."
Blues still have injury and illness issues and were glad to welcome back Lucy Staniforth and Rachel Williams, albeit as a unused substitute, for the visit of Chelsea.
It has meant players being asked to do jobs out of position, and the Academy teenagers stepping to the fore.
Said Tejedor: "In general I am pleased they are able to adapt, and play different positions. Also, the Academy girls coming into the team and fitting in.
"We do need to understand, of course, that every time we change a player and put her in a different position it is not always easy.
"Sometimes you can change and it is not too bad because the positions are similar. But there is always that difficulty, even if the players shows a good attitude and gives everything.
"You need time to get used to a new role and you ideally need some experience of it.
"It's like asking me to - I don't know - drive a truck: I've never done it, I can try and do my best but I will probably crash a couple of kilometres down the road!"
There will be a determination among the players once battle commences against Spurs, not least fired by the lingering memory of what happened against Chelsea.
"Sure, there will," said Tejedor. "I am not disappointed with the players' attitude. They are doing what they need to do.
"We sat down and analysed the goals from Chelsea. We recognised what was good and what wasn't good and what we need to change.
"We will continue to work harder, as I have mentioned, and we also depend a lot on the recovery of our players. Especially when they are experienced, top level players.
"But this is what is before us and we have to give all we can to make our position in the league better."
