The Hammers will head into the game on the back of a 1-1 draw with Sunderland at the Stadium of Light last weekend.
Prior to that game, Sam Allardyce’s side had won their last three matches: against Newcastle United (home), West Bromwich Albion (away) and Swansea City (home).
London outfit West Ham will be favourites to win today, especially as Leicester are struggling for points.
The Foxes are currently at the foot of the Premier League table with just 10 points from 16 matches.
Here is how West Ham and Leicester will line up for today’s match.
