Red-hot Jame Vardy piled the pressure on Arsenal boss Unai Emery as the Leicester striker continued to haunt the Gunners.
The forward scored his ninth goal in nine games against the Gunners to inspire the Foxes to a 2-0 win and into second in the Premier League.
Vardy, the top flight’s 11-goal leading scorer, also set up James Maddison’s clincher as Emery’s side slumped to a limp defeat at the King Power Stadium.
Alexandre Lacazette wasted Arsenal’s best chance and Pierre-Emerick Aubameyang had a goal disallowed but the visitors were poor.
The Gunners, winless in the Premier League for over a month, slipped eight points behind the top four with Emery’s position under increasing scrutiny.
Leicester now sit five points behind leaders Liverpool – who host Manchester City on Sunday – after a deserved fifth straight win.
It allowed the Gunners to briefly look dangerous and Lacazette’s weak shot was gathered by Kasper Schmeichel.
They had contained any early Leicester threat but were guilty of poor distribution as Emery’s men tried to play out from the back.
Sloppy passing continued to blight the Gunners and Bellerin, making his first Premier League start since January after injury, gifted the ball to Ayoze Perez to fire over.
Encouraged, Leicester pressed and only Calum Chambers’ telling touch on Perez’s low cross denied Vardy after 33 minutes.
Arsenal were there for the taking but the Foxes’ lack of intensity aided the visitors.
Maddison’s free-kick flew just over three minutes before the break and Harvey Barnes miscued a header.
Arsenal then thought they had opened the scoring after 55 minutes when Aubameyang converted Sead Kolasinac’s cross, only for the striker to be correctly ruled offside.
