Chelsea dropped points in their second straight Premier League match on Saturday, losing 1-0 to West Ham United.
The Blues were the better team before the break, but Christian Pulisic missed several great chances to hand them the lead. That proved costly, with Aaron Cresswell opening the scoring early in the second half.
The Blues had won six straight Premier League matches before their previous outing, a 2-1 loss to Manchester City.
What's Next?
Both teams will be in action on Wednesday, when Chelsea host Aston Villa and West Ham visit Wolverhampton Wanderers.
