Goals in each half from James Maddison and Harvey Barnes earned Leicester City a 2-0 win over Southampton at King Power Stadium.
Maddison fired the Foxes ahead on 37 minutes when he collected a pass from Youri Tielemans, and finished emphatically into the roof of the net from a tight angle.
Leicester were twice indebted to goalkeeper Kasper Schmeichel, who, on his 400th appearance for the club, superbly denied Che Adams and Ryan Bertrand.
Stuart Armstrong struck the crossbar as Southampton pressed for an equaliser, while at the other end, Jan Bednarek cleared Barnes' shot off the line.
However, Barnes did strike in stoppage time, keeping his cool to finish beyond Alex McCarthy after racing on to another assist from Tielemans.
Leicester, now unbeaten in five Premier League matches, go second on 35 points, a point behind leaders Manchester United, who face third-placed Liverpool on Sunday.
Southampton drop to eighth on 29 points.
