Spurs have endured a difficult couple of weeks; firstly losing successive Premier League games to London rivals Chelsea and Arsenal, as well as crashing out of the Europa League at the hands of Portuguese giants Benfica - piling the pressure on manager Sherwood.
The novice boss took over in December after the sacking of Andre Villas-Boas, but recent results have placed Sherwood's long term future at the club in doubt, with chairman Daniel Levy reportedly looking at more experienced managers to take over at the end of the season, with Holland manager Louis van Gaal the favourite.
But there are still a number of games to play this season, and with a top four finish unlikely but not entirely out of the question, they simply had to beat Southampton today - and their quest for three points took a hit early on, as Jay Rodriguez and Adam Lallana capitalised on some slack defending to put the Saints 2-0 up.
Yet two goals either side of half time from Danish playmaker Christian Eriksen drew Spurs level, and with time running out, Gylfi Sigurdsson hit home a long range strike to hand Spurs all three points - and with mounting pressure on the Tottenham boss, Sherwood simply couldn't hide his delight on the touchline after Sigurdsson's last gasp winner.
It may not be enough to keep the permanent job at White Hart Lane, but it was a much needed bonus for a Spurs side that have struggled in recent weeks.
