Tottenham were beaten for the ninth straight league game to heap pressure on manager Rehanne Skinner.
Spurs, who have not won since October, lost 2-1 at Liverpool to leave them just two points above bottom-of-the-table Leicester.
Rosella Ayane had given Tottenham the lead in the first half but Emma Koivisto equalised five minutes later before Missy Bo Kearns put Liverpool 2-1 ahead before the break.
Spurs, who were also knocked out of the FA Cup by Reading two weeks ago, face a crucial home game with Leicester on Wednesday before taking on north London rivals Arsenal on March 25.
