Slaven Bilic believes Diego Costa should have been sent off in West Ham’s 2-1 defeat at Chelsea.
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.
James Collins looked to have earned Bilic’s side a point by cancelling out Eden Hazard’s penalty.
Bilic told Sky Sports: “He had already been booked and it wasn’t reckless and I don’t think that it was deliberate but it was quite late, the ball was already gone and he could have, or should have, been booked again, which would mean a red card.
“But, to be fair, I’m not frustrated because of that, I’m frustrated because we conceded a very late goal and that’s what makes me sad.”
