The Foxes' impressive start to life under Claudio Ranieri continued as they took a deserved 27th-minute lead in east London as Japan international Shinji Okazaki scored his first goal for the club.
Riyad Mahrez netted twice for the visitors on the opening-day and the Algerian winger was on target once more to give Ranieri's men breathing space at the interval. Despite boasting a deserved lead at the break, West Ham were able to hit back in the second period when Dimitri Payet reduced the deficit on 55 minutes.
The match descended into chaos in the closing minutes, as Hammers ‘keeper Adrian pushed forward from a corner in order to aid his side’s cause.
In an attempt to recover possession as the corner ran astray, he sunk his studs into Jamie Vardy’s stomach, finding himself rewarded with little more than a red card for his efforts.
