A win for the visitors will reinstate Chelsea's 10 point lead at the top of the table
West Ham host Chelsea in Monday's only Premier League match and a win for the visitors will give them a 10 point lead over second place Tottenham at the top of the table.
Andy Carroll might be back in the starting line-up tonight as he goes looking for his 50th Premier League goal although Michael Antonio will serve a one match ban.
The sides have met twice this year already with Chelsea winning 2-1 at Stamford Bridge in August although the Hammers knocked Chelsea out of the EFL Cup with a 2-1 home win in October.
Chelsea go into the match unbeaten in their last six league games while West Ham have picked up five points in their last three games.
The visitors have lost two of their three away London derbies in the Premier League so far this season, at Arsenal and Tottenham, but they won at Crystal Palace.
