Brighton boss Chris Hughton admits he's angry after defeat at Cardiff City.
After Dale Stephens received a controversial straight red card for a challenge in the first half, Sol Bamba fired home in the closing stages to deny the Seagulls a point in Wales.
Hughton said, “We're frustrated and angry because when you're down to ten men for such a long period of time, you certainly warrant getting something out of the game.
“There are two big decisions — the first one is the red card and I think that particular challenge can go any way. What Dale [Stephens] has done is give the referee a decision to make.
“I've certainly seen worse with the studs showing very early. There's not great contact with the player — some referees wouldn't have given it, some would have done, and that bit I understand.
“What I find harder to understand is, particularly at that stage of the game, a linesman that's in the position he's in getting that one [Sol Bamba's goal] wrong.
“We've seen it on numerous occasions and he's in an offside position. That's the frustration and anger. For me it's a comfortable and easy decision to make."
