Albion boss Chris Hughton claims Marco Alonso should have been sent-off in the 2-1 home defeat by Chelsea.

The Spanish left-back was cautioned by referee Stuart Attwell in the 88th minute for holding back Solly March as Albion's goal scorer threatened to race clear from sub Yves Bissouma's pass.

Alonso had earlier fouled Anthony Knockaert and also prevented the Frenchman chasing a ball that was running out of play with an outstretched arm.

Hughton said: "My first impression was that it was a red card (challenge on March). Having seen it again, I do understand that it's a difficult decision with the pace on the ball and whether Solly would have been right through.

"I can understand that a bit. I still think there are referees who would have send him off as the last man. But he should have been on a yellow card anyway.

"He pulled back Anthony, which is generally always a yellow card. There were two incidents. He should have been on a yellow. If someone pulls someone back on more than one occasion, it should be a yellow."

Hughton was told why Alonso did not see red.

He said: "The fourth official, Kevin Friend, explained it to me. He didn't think Solly would have been in control of the ball. Because he's last man, and because of the intensity of the game, there would have been a lot of referees who would have sent him off."

Sub Florin Andone was involved in an incident with David Luiz shortly after which resulted in a yellow card for Albion's Romanian striker.

Hughton said: "The question will be, and others will see it again, is how much contact there is. There is definitely a kicking out by David Luiz.

"How much contact is on Andone, I don't know. But the intent is there. That action is certainly there. The referee would have to make a decision on whether he penalises Luiz on the action itself or the content."
