The side finished the month in second place, just two points behind league leaders Leicester City after claiming victories over Norwich, Watford, Manchester City and Swansea.
But while the wins against the two newly-promoted sides and the Swans were vital to keeping their momentum going, it was surely the game at the Etihad Stadium that the club will look back on as a crucial moment in their season if they do go and win the title.
Having dictated much of the game - and been rewarded with Harry Kane opening the scoring from the penalty spot - the momentum seemed to shift in City's favour when Kelechi Iheanacho equalised with just over 15 minutes to go.
However, Christian Eriksen's late winner sent a real statement to the rest of their title rivals that this Spurs side had all the quality to pick up victories, but now also had the steel and fighting spirit needed to compete at the very top over 38 games.
And while March has started without a win in all competitions, the form they showed throughout February will surely convince Pochettino that they can still claw back the five-point gap that currently exists between them and Leicester.
