London - Southampton gained revenge for 9-0 thrashing at the hands of Leicester in October to continue their resurgence with a 2-1 win at the Foxes on Saturday.
The Saints claimed their fifth win in six games at the King Power Stadium as they came from behind against the side second in the table.
Dennis Praet fired the hosts into an early lead, but Stuart Armstrong's deflected effort quickly pulled Ralph Hassenhuttl's men level.
Danny Ings then scored his 10th goal in 11 games eight minutes from time and the visitors survived a late scare when Jonny Evans's header was ruled out by VAR for offside.
