West Ham United visit Stamford Bridge to face Chelsea tomorrow, and after losing one London derby against Tottenham Hotspur last weekend, the Hammers will hope to come out tops this time out. Manuel Pellegrini’s men are without a win in their last seven games, losing five of them, and they have their work cut out for them against Frank Lampard’s youngsters. Chelsea’s defeat at the hands of Manchester City last weekend was their first in seven league games, and having won the six games prior to that, they will look to bounce back against West Ham.
