West Ham manager Slaven Bilic, however, was understandably frustrated but surprisingly lenient.
“Diego Costa had already been booked,” he said. “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’m not frustrated because of that, I am frustrated because of the late goal.
Hazard believed Chelsea played “like tigers” and was pleased his goal helped to bury the memories of his poor season last term – when he failed to score a league goal until April.
“We played every minute like tigers,” he said. “I missed my last couple of penalties. Oscar wanted to take but I said no it is my turn. It is always good to score a penalty.
