The Londoners find themselves in sixth place going into the game, still with an outside chance of qualifying for the UEFA Champions League, although they were knocked out of the FA Cup on Wednesday.
The Hammers have been tremendous on the road this season, losing just four of their last sixteen games away from home (W6, D6, L4). Despite winning just one in their last five (D2, L2), the away side are still currently in a Europa League spot with just six games remaining of the current season.
Leicester City on the other hand have been in fine form. The Foxes are flying in the league, currently seven points clear at the top, and just three league wins away from being crowned Premier League champions for the first time.
Jamie Vardy scored a brace in last weeks 2-0 win away to Sunderland, a game which say the title chasers keep a club record fifth clean sheet in a row.
Between the two sides there are four players shortlisted for the PFA Player of the Year award (Leicester: Jamie Vardy, Riyad Mahrez, N'Golo Kante. West Ham: Dimitri Payet), such are their respective successes this term.
West Ham find themselves with no fresh injury concerns ahead of this clash.
Diafra Sakho is set to miss out for a third consecutive game with a knee injury, but defenders Winston Reid and Sam Byram are available for selection. Byram has been absent since February and was cup tied for Wednesday's FA Cup clash, whilst Reid had only a minor problem.
Claudio Ranieri has a fully fit squad to choose from for the tie. In eleven of their last thirteen games he has elected to start the same XI and could do so again here.
- The two sides have met 125 times previously. West Ham have a slightly better record, coming out on top 51 times, whilst Leicester have 45 wins.

- Eleven of Leicester's fourteen clean sheets have come in their last fifteen matches.
