Michy Batshuayi scored on his first Premier League start for Crystal Palace and Wilfried Zaha struck twice against Leicester City.
Crystal Palace marked a record-breaking game for manager Roy Hodgson with a 4-1 win at slumping Leicester City, who have now lost four on the spin at home.
Palace boss Hodgson - who became the oldest person to take charge of a team in a Premier League fixture - watched on as his side clincially defeated their hosts to increase the pressure on opposite number Claude Puel.
Michy Batshuayi reacted swiftly to divert a wayward long-range drive from James McArthur beyond goalkeeper Kasper Schmeichel for the only goal of the first half at the King Power Stadium.
