The remarkable rise of Oumar Niasse goes on, with a match-winning double here to add to his strike in the League Cup in midweek. The manager who tried to shove him unceremoniously through the exit door will have felt sheepish, to say the least, when his Senegalese substitute turned the latest lacklustre Everton performance around.
Kane’s header and low strike gave the visitors a 2-0 half-time lead before midfielder Christian Eriksen fired home the third in the 60th minute.
Lukaku broke the deadlock on 20 minutes, converting the rebound after Saints goalkeeper Fraser Forster parried his header from Ashley Young’s cross.
Antonio Conte’s side took the lead after only two minutes, Morata showing composure to latch on to Cesar Azpilicueta’s long ball over the top and slotting it past goalkeeper Jack Butland.
The Foxes won 2-0 in their Carabao Cup third-round meeting on Tuesday, but the Reds exacted revenge on their return to Premier League action.
