Rotherham manager Leam Richardson was left perplexed by referee Geoff Eltringham’s decision to award West Brom a penalty in the Baggies’ 2-0 win over the already-relegated Millers at the Hawthorns.

Brandon Thomas-Asante had handed the promotion-chasing hosts a 23rd-minute lead before Eltringham pointed to the spot when the striker’s shot struck Lee Peltier, though replays showed he was outside the box and the ball appeared to strike his face.

John Swift netted the resulting penalty in first-half stoppage time to settle the Championship fixture.

Richardson said: “I’ve not seen that before. The assistant was maybe 10 yards away looking down the line of it. Then he goes and books my assistant manager (Rob Kelly) for telling him ‘the linesman can help’. It was a wrong decision, and a poor one in my opinion. It changed the full outcome of the game.

“The first goal we gave away was poor, but then I thought the second one changed the whole complex.

“Someone said in another interview that those decisions go against you when you’re down there, but that’s a disgusting way of looking at it. You should have a consistency of professionalism regardless.

“I never question anyone’s integrity, but I can’t explain that decision.

“We’ve had a number of similar decisions and apology letters, but I have no interest in that. You can’t get those decisions wrong.”

Asked if he would report the match officials, Richardson said: “What? And get another apology letter?”

Richardson’s opposing number Carlos Corberan, who has guided West Brom into fifth and nine points clear of the chasing pack with four matches left to play, said he had not seen a replay of the incident.

“I didn’t see the action back,” he said.

“I knew from the level of the protests from the players and the staff, I understood that there was no doubt that it was the wrong decision. In these situations, you always want fair decisions.

“Later in the game there was another decision, maybe a foul on Asante inside the box, that the referee didn’t whistle.

“If the referee did something wrong, he can, let’s say, compensate for this, but during the year, unfortunately the referees haven’t had the support to guarantee the right or wrong decisions. Live, they need to make quick decisions.

“Sometimes they make mistakes because everyone does. It happens in your favour sometimes, sometimes not. We have, this year, received a lot of wrong decisions against us, which we don’t want in the same way we don’t want any type of advantage in the decision.

“If the action wasn’t a penalty, it’s a pity, but hopefully it’s a compensation of something that we have suffered from before.”
