Jamie Vardy scored a last-minute equaliser for Leicester City as the visitors had to come from two goals down to rescue a point at St Mary's.
The Saints took a convincing lead going into the break, as Jose Fonte and Virgil van Dijk scored in a dominant first-half display from the home side.
The Portuguese centre-half headed home from a corner midway through the first 45 minutes, while his defensive partner doubled the lead shortly before the interval.
Claudio Ranieri's side started the second 45 minutes brighter than their opponents, as Nathan Dyer had a good chance from a set piece to get the Foxes back into the game but the on-loan Swansea City winger was hurried by Van Dijk and wasted his opportunity.
Southampton had a penalty claim waved away shortly after, as Graziano Pelle flicked the ball up on Robert Huth's arm in the area, with the referee deeming it unintentional by the German defender.
However, Leicester got themselves back into the game through the Premier League's current top goalscorer, as Vardy scored his sixth goal in as many games, after Dyer created the opportunity by running at the Saints backline, allowing space for the England international to get in behind and exploit the space.
Vardy then had the chance to score his second of the game and his side's equaliser but blazed his shot well over, with Kelvin Davis already beaten when the shot fell to Vardy.
Despite his previous miss, the Foxes got their equaliser through the England striker who managed to convert his one-on-one attempt by blasting his shot into the roof of the net.
The goal keeps the 28-year-old as the top goalscorer in the league with nine, three ahead of Sergio Aguero in second.
The point keeps Leicester in fifth while the dropped points by Ronald Koeman's side keeps them eighth.
