21:48: So Chelsea win a tough game against a resilient West Ham side, despite Mourinho's side not being at their best. However, that's what champions do, and this Chelsea team definitely look like they could go on to win the league, after keeping their five-point gap over Manchester City with a game in hand - even with City winning tonight. Whereas, West Ham drop into tenth place with Stoke winning 2-0 at home against Everton.

19:30: Just 15 minutes to go until kick-off!
19:23: Pictures of the Boleyn Ground filling up as fans enter the stadium with kick-off soon approaching! (via @whufc_official on twitter).
19:19: Chelsea boss Jose Mourinho on tonight's team selection, "The players are fine, a good reaction after the League Cup final. The players are strong, we don't have a game at the weekend and they are ready for this. We changed Oscar for Willian because he is faster and more direct. We have the two best two goalkeepers in the country so it doesn't matter who plays. Petr Cech had the happiness of the final, so Courtois is compensated by playing in this and the Champions League."
19:15: The teams are out warming up! Here is West Ham goalkeepr Adrian being tested (via @whufc_official on twitter).

Other than that, Mourinho has made two changes to the side that played in the Capital One Cup final. Thibaut Courtois replaces Petr Cech in goal and Oscar is preferred to Willian who drops to the bench.

18:20: Tonight's venue - the Boleyn Ground
18:10: For a full in-depth preview of tonight's game, look no further - https://www.vavel.com/en/football/premier-league/458264-west-ham-vs-chelsea-blues-look-to-increase-gap-in-title-race.html
18:05: In terms of team news, for West Ham, striker Carlton Cole is a doubt and midfielder Morgan Amalfitano is still completing his suspension following a red card in the FA Cup against West Brom. For Chelsea, as previously stated, Nemanja Matic is completing his two-match supsension and John Obi Mikel remains doubtful.
18:00: He further went on to comment on his plan to protect his players from being affected by the result of the Liverpool-City game, "I knew that was an impossible mission, but I didn't want the television on in the hotel or on the bus. I told them I didn't want any kind of manifestation or disappointment if City scored in the last minute, or Liverpool won. I wanted complete silence. We were successful on that. But one member of my staff jumped up in the bus. Silvino (Louro - assistant first-team coach). I wanted to kill the guy. He broke the rule."
17:56: Mourinho himself commented on the title race following Manchester City's 2-1 loss to Liverpool on Sunday. "It's in the hands of everyone. We have lots of difficult matches to play. City have difficult matches. (Manchester United) are in the title race too. Liverpool (defeating City), I predicted that," claimed the Chelsea manager. Despite many people joking that his side had completed the double on Sunday following Manchester City's result, including Match of the Day presenter and former England international Gary Linekar.
17:51: Ahead of tonight's game West Ham goalkeeper Adrian spoke to the club's website about previous meetings with Mourinho, one of which being a 1-0 victory over Real Madrid in 2012 for Real Betis, "I don't know if Mourinho remembers me but when I play against him I have got some good results. Personally, I feel good when I play against Mourinho."
West Ham Chelsea
17:47: "The best players in the world can make mistakes, the best players in the world miss penalties, the best goalkeepers in the world can make mistakes. This gentleman is one of the top referees in this country. He's one of the top referees in European football. He can also make mistakes. He clearly made mistakes in the Everton-Liverpool game, and he made four important mistakes yesterday." We'll spare you from having to read the whole rant but Mourinho certainly did have a justified case and because of those incidents, Nemanja Matic will miss tonight's game.
17:42: Chelsea manager Jose Mourinho in particular disagreed with many of the referee's decisions, an opinion which he expressed in a rant on Sky Sports' Goals on Sunday. "To say clearly that at half-time Burnley would be playing with 10 men and Chelsea should have two penalties, and normally be winning 3-0. Or let's put the possibility of missing one the two penalties, winning 2-0 and playing against 10 men. The reality is that in the end we play with 10 men and we lost the points," he said. "His (Atkinson) opinion is wrong because the arm stops the ball from hitting the target. There's no space for interpretation. It is a penalty or it is not a penalty. He's far away. He (Kightly) is not one metre. He's not a few inches. The ball hits the target if this is not a penalty."
BPL Live Updates
17:38: Chelsea head into this fixture favourites and rightly so. The league leaders recently defeated rivals Tottenham Hotspur to win the Capital One Cup on Sunday, whilst second-placed Manchester City lost away at Liverpool, giving Chelsea a five-point lead and a game in hand at the top of the table. However, their last outing in the BPL saw them draw 1-1 at home against Burnley amidst some refereeing controversy. Chelsea were appalled with referee Martin Atkinson's display and felt that Burnley striker Ashley Barnes should have been dismissed for two incidents during the game, and Chelsea should have been awarded a penalty for a foul on Diego Costa and one for a handball which were both deemed penalties by many TV pundits but not by the referee.
17:35: West Ham have conitnued their recent poor form as of late, losing at home on the weekend 3-1 against ten-man Crystal Palace, extending their winless run to seven games. This poor form has seen them slip down to ninth in the BPL table, level on points with tenth-placed Stoke City. Relegation won't be a worry for the Hammers but a chance at European qualification seems to be slipping away as their poor form continues to occur. Unfortunately for them, their opponents tonight - Capital One Cup winners and current league leaders Chelsea - aren't exactly going to be a walkover.
