Leeds manager Daniel Farke insisted his side should have had a penalty after losing more ground in the battle for automatic promotion from the Championship with a 1-0 defeat at West Brom.

Farke was frustrated at referee Graham Scott’s refusal to award a spot-kick for a challenge by Baggies defender Cedric Kipre on Wilfried Gnonto in the 30th minute as Leeds suffered a second successive loss for the first time this season.

Seven minutes later, Grady Diangana scored the only goal to make it back-to-back home wins for the Baggies and move them to within three points of fourth-placed Leeds.

“Why should he go down when he’s one against one with the goalkeeper?” said Farke.

“I think the whole stadium saw the situation but they decided not to give us a penalty.

“Normally if that had been a penalty, it would also have been a red card.

“There was no intention to play the ball so it was a decisive moment in the game.

“It changed so much against a side who was so focused on defending.”

Diangana’s goal came off his knee after his first attempt was blocked by Joe Rodon after Okay Yokuslu split the Leeds defence for Jed Wallace to cross.

Despite having 63 per cent possession, Leeds failed to seriously test goalkeeper Alex Palmer and Farke admitted his team lacked a cutting edge.

“We started well, but the last two or three per cent brutality to get the shot away was not there – that’s why we lost,” said Farke.

“We changed our base formation and brought on offensive players, they brought all their defensive players on and showed great commitment to block our strikes.

“We needed that last few per cent brutality to win those headers or to shoot after a really tidy first touch to get the shot away.”

West Brom head coach Carlos Corberan saluted a “special” performance from his side.

“It was special in terms of the commitment the players put into the game,” he said.

“We knew that to beat Leeds you can only have these special wins if you have a lot of good players, if you’re a very strong team and you play with a lot of team mentality, team spirit and personality.

“We found good possibilities to cross from our right side with Jed Wallace, and from one of these actions, we scored.

“The second half started balanced, but then they changed formation and were very aggressive with a lot of attacking players and we had to adapt our shape and to defend the goal we scored.”

On Leeds’ claims for a penalty, Corberan added: “I don’t know because I haven’t seen the action back yet.

“But Leeds have some of the best players in the last third of the pitch and normally they want to challenge your defenders a lot.”
