Diego Costa and Eden Hazard scored in the second half as Chelsea finally broke down Leicester's stubborn resistance for a 2-0 victory in the Premier League on Saturday.
The newly promoted visitors had threatened a major upset until Costa controlled a deflected pass from Branislav Ivanovic in front of goal and slotted the ball past goalkeeper Kasper Schmeichel in the 63rd minute. It was Costa's second goal in two league games for Chelsea, having joined from Atletico Madrid in the offseason.
Hazard then put the result beyond doubt with a solo effort in the 77th, cutting in from the left and sending a low shot inside the far post.
Leicester missed a couple of good chances before Costa's opener, including when David Nugent came clear through on goal but had his shot saved by the onrushing Thibaut Courtois.
