After a goalless first half, Vardy fired the hosts ahead from the penalty spot after Adam Masina had fouled Jonny Evans. Maddison then made sure of the win in stoppage time, breaking away before slipping the ball past Ben Foster in the Watford goal.
The visitors were solid and hinted at a threat on the counterattack. And yet Leicester should have opened the scoring in the second minute after a move nicely begun and terribly finished by Ayoze Pérez. The Spaniard did everything right until he slammed the ball over the bar from 10 yards following a smart setup by Vardy. Pérez flopped again four minutes later, failing to make a clean connection from eight yards out after another Vardy pass.
Watford’s game-plan was clear, to defend in numbers and break on the counter-attack, with winger Ismaila Sarr attempting to pressurise Leicester left-back Christian Fuchs, in for the injured Ben Chilwell.
