The hosts are going through a difficult phase and have had a bad start to the season. The 1-1 draw against Fulham last weekend may be acceptable for many teams, but for the Hammers it is not enough. The demands in the Premier League are high and now Chelsea is coming up as an opponent that doesn't make things any easier. Although West Ham is hoping for more stability, the match against the Blues will be a real challenge. Chelsea, on the other hand have been enjoying lately. The 1-0 win against Bournemouth gives the Blues confidence, and with a deep squad they can easily prepare for the upcoming Conference League without losing strength in the league. Things are going particularly well for the Blues away from home. They have won their last four away games and could now extend the series to five wins in a row. The last peak of this kind was under Thomas Tuchel three years ago. Head to head games also speaks in favor of Chelsea. Under new coach Enzo Maresca, they have also won both of their away games this season.
