Chelsea's first away game of the Premier League season takes them to the London Stadium to face West Ham United on Friday night, with both sides looking for their first win of the new campaign.
Chelsea played out a goalless draw against Crystal Palace at Stamford Bridge last weekend, with a performance that underlined a serious need for improvement should they want to challenge right at the top of the league.
West Ham's opening day performance was desperate. A buoyant Stadium of Light saw Sunderland pile the pressure on Graham Potter, as they won 3-0, and reduced West Ham to barely a sniff in front of goal, with both Jarrod Bowen and Niclas Füllkrug having no real chances in front of goal.
Here's everything you need to know ahead of the game.
