Ralph Hasenhuttl says Southampton produced the best performance of his tenure as they fought back to beat Tottenham and damage the hosts' bid for a Champions League spot.
Che Adams headed the winner in the 82nd minute, just three minutes after Mohamed Elyounoussi beat Hugo Lloris in almost identical fashion to level.
Southampton defender Jan Bednarek had earlier turned into his own net to open the scoring when under pressure from Son Heung-min following Pierre-Emile Hojbjerg's cut-back.
But Armando Broja levelled soon after in what was a dominant first-half performance from the visitors in which Romain Perraud also struck the crossbar.
