The race for the Golden Boot is intensifying following the resumption of the 2019/20 season as the Premier League's sharpest shooters battle it out.
Ings has scored three times in his last three appearances, his form in sharp contrast to that of Vardy, who has only netted twice since 21 December.
Should he see off the challenge of the Leicester City striker and the other contenders, Ings would become the first Saints player to claim the Golden Boot, which is presented by Cadbury.
He is, however, some way off matching his tally of 32 goals when he won the award for the first time in 2017/18.
Team-mate Mane is still in contention after he also netted in the 4-0 victory over the Eagles.
They have both gained ground on Arsenal forward Aubameyang, who has failed to find the net in each of his last four matches.
Up next for the 31-year-old is a home meeting with bottom side Norwich City on Wednesday.
