There may be some rearrangement at the top of the Premier League table, if Chelsea win this match by more than 1 goal and Manchester City win their today's visit. This will mean that Arsenal will drop to the third position. Although the points difference is minor, this will definitely be a hit for Arsenal, which have a hard fixtures up ahead in the next three rounds.
Chelsea is in superb form, winning 11 of their last 12 matches in the Premier League. The blues are undefeated at home in the league, where they score an average of 2.14 goals per game. The statistics of the meetings between these two teams is entirely in favor of Chelsea, winning 7 of their last 8 games at home to West Ham. It seems that Jose Mourinho will make another step towards winning the title.
For West Ham the situation is not at all pleasant, as at the moment the team is in the relegation zone. With regard to the performance of the "hammers" away from home, there is no evidence that they have strength even for a point in this match. The team have won 2 games away from home this season and rarely manage to score a goal, reaching an average of 0.75 goals in an away game.
