West Ham United manager Slaven Bilic has insisted that he is "not frustrated" by the referee's decision not to send off Chelsea striker Diego Costa for a lunge on goalkeeper Adrian.
The controversial striker, who had been yellow-carded earlier in the match, committed the foul while Adrian tried to move the ball clear with his feet.
Referee Anthony Taylor opted against punishing Costa, who went on to score an 89th-minute winner in the 2-1 victory.
"Diego Costa had already been booked," Bilic told Sky Sports News. "It was not reckless or deliberate but it was quite late, the ball had come. He could have been booked again and so a red card. I am not frustrated because of that, I am frustrated because of the late goal."
The Hammers' next league game will be at home to Bournemouth on Sunday.
