West Ham manager Slaven Bilic felt Diego Costa was lucky to still be on the pitch to score the late winner as West Ham lost 2-1 at Chelsea in the Premier League.
Costa, who drilled home from 20 yards in the 89th minute, escaped punishment for a late tackle on Hammers goalkeeper Adrian having already been booked for dissent.
Bilic told Sky Sports that the striker should have been sent off for the 67th-minute challenge, even if he did not mean to connect with Adrian's leg.
