Midfielder Dale Stephens says Albion must make sure it is a "one-off" after a Bournemouth battered the Seagulls 5-0 at the Amex.

Albion winger Anthony Knockaert was sent off in the second half for a reckless tackle on Adam Smith with the hosts already 2-0 down top goals from Dan Gosling and Ryan Fraser.

It got worse the Chris Hughton's side as David Brooks, Callum Wilson and Junior Stanislas added further goals to pile on the misery.

Stephens, speaking to Match Of The Day, said: "It's a very disappointed changing room. We're all very disappointed.

"We were miles away from what we're used to today. But we move on. We've got a massive game on Tuesday.

"There were some strong words said in the changing room like there should be. We just need to make sure it was just a one-off.

"We're in a position in the league where it's still in our hands and we can still do something about it. So that starts with a big game on Tuesday."

Stephens now wants to see an immediate reaction with Cardiff, who occupy the last relegation spot five points behind Albion visiting on Tuesday.

He added: "It's a bad, bad day. Bournemouth played well and we didn't. We didn't build on what we've been doing well this season.

"We don't use excuses. We pride ourselves on hard work and preparation and now we've got a big game to move on to on Tuesday (against Cardiff).

"The pressure's on now. We've got to stand up and be counted on Tuesday."

Stephens revealed Knockaert apologised to his team-mates after his red card.

He said: "Whether it’s a red card or not, the referee’s made a decision and he’s put himself in that position where he’s allowed the referee to [send him off]. He’s disappointed. 

"We need our best players on the pitch and he’s one of them. He’s apologised. We were getting beat at the time, frustrations were high and he’ll make sure he won’t do it again."
