James McArthur has reflected on Crystal Palace’s capitulation against 10-man Brighton at the Amex Stadium.

Despite Shane Duffy receiving a straight red card, the visitors were picked apart by goals from Glenn Murray, Leon Balogun and Florin Andone.

Palace would dent the lead through a Luka Milivojevic penalty but were ultimately second-best throughout in a heated M23 derby clash.

McArthur said: “It wasn't good enough, especially in the first half. We created some opportunities but to give them three goals is not acceptable.

“Even in the second half when we were pushing we still didn't put their goalkeeper [Matt Ryan] under enough pressure when they've got 10 men.

“Poor performance all round and not acceptable. The only thing we've got that's maybe working for us as players is we'll get a game very fast to try and make it right.

“When you've got that full week then it's hard and it eats away at you. Now, obviously, we've got a couple days to deal with the disappointment but we need to get going again and try to make it right by winning at West Ham.”

The midfielder found himself in trouble when he was adjudged to have brought down José Izquierdo inside the box for a penalty.

Murray would convert from the spot, his eighth league goal this season, but McArthur insists he “100 percent won the ball”.

It’s added disappointment for Palace after they eased past Burnley thanks to strikes from him and Andros Townsend.

Now the rest of their December calendar involves West Ham, Leicester City, Manchester City and Chelsea.

McArthur added: “We didn't start great. It's so important to start well in the Premier League, we didn't start great.

“It's not an excuse but I think the penalty decision is a big decision in the game, goals change games.

“If that doesn't happen then it's 0-0, and if we get the first goal it changes, but we've still conceded two after that so that's a disappointing factor.”
