Current Premier League leaders Chelsea have only lost three of their previous 21 games in all competitions — but all three came against fellow Londoners.
West Ham, Arsenal and Tottenham have all defeated the Blues at home this season and the former has the chance to make it two in a row tonight.
However, they will have to do it without both their main striker and their make-shift striker, with Andy Carroll and Michail Antonio both out.
Instead Andre Ayew may be the one to lead the line, with West Ham lacking options up top following Simone Zaza’s departure to Valencia.
It’s unlikely to be enough, though, with Chelsea flying at the top of the table, sitting seven points clear of Tottenham and eight clear of Manchester City.
The west Londoner’s will be buoyed by West Ham’s woeful defending on their own patch of late having conceded 13 goals in their previous games.
They may have kept a clean sheet against Crystal Palace, but they conceded nine against City in the space of a month in the league and cup.
With Eden Hazard flying at the moment, and Diego Costa as deadly as ever back Chelsea and over 2.5 goals at 2.37.
