South London takes on East London as Chelsea host West Ham at Stamford Bridge on Saturday

West Ham could not have picked a worse time to play their London rivals. The Irons are currently bang out of form, having not won any of their previous eight matches, leaving them three points off the relegation zone.

This current form has put severe pressure on boss Manuel Pellegrini and as the current trend of managers getting sacked remains constant, a loss here might see the end of Pellegrini’s stay at the London Stadium.

Chelsea are in the polar opposite situation to the Hammers. Blues fans are loving life under Frank Lampard and his side are an entertaining and wonderful side to watch this season.

The Blues will be looking to bounce back after their 2-1 defeat to Manchester City last week and look to keep up the pressure on the top of the table.

Despite their current form, this West Ham side is still one that is full of quality players, so Chelsea can still expect a fight from the Irons and will need to deliver a professional performance if they want the three points.

Here are the key battles that we think will decide the game:
