Ashley Barnes led the rallying call as the Clarets left London licking their wounds for a second successive week.
A second-half strike from Barnes sparked a Burnley fightback after Arsenal had led 2-0 at the Emirates Stadium.
Sean Dyche’s men had the Gunners on the back foot as they hunted down a point to take back to Turf Moor ahead of the Boxing Day visit of Everton.
But after a late goal brought them defeat at Tottenham a week previously, the Clarets were undone again as Arsenal added a third goal on the break in injury time to leave Barnes with nothing tangible to show for his first goal since September.
“It was nice to hit the back of the net. I haven’t done it for a while and hopefully that continues and we can get out of the bottom three,” said the striker, who gave the Arsenal back line a torrid afternoon.
“I try to give my best and I always will for the shirt and for the club and put everything out there.
“I got a goal but the main thing is the points that we need to start picking up.
“We’ll dust ourselves down and we’ll get ready for Wednesday and hopefully come out with the three points.
“We knew we had two tough games on the bounce and now we’ve just got to try and pick up as many points as possible. We’ve still got a long way to go and we’ll do that.
“These games are important and for everyone to get behind us and us to put in the performances we have done in the last few games.
“I am confident with that group of players in the changing room and the work we do for each other.
“We’ve still got half of the season left. I have no qualms we will get out of it.”
The Clarets head into Christmas in the bottom three and with just three wins so far this season.
But since the start of December they have played with renewed purpose.
And while an unforgiving fixture list – including games against three of the Premier League's top-five sides – has made points hard to come by, Barnes believes they deserved more against the Gunners who moved level with Chelsea in the race for a top-four place.
“It was another tough one to take. It’s obviously against a good side but I thought we did well again today,” he added.
“It’s just unfortunate the manner of the goals we’re conceding.
“At 2-1 it could have been a penalty on Longy when he got pushed in the back and a few decisions didn’t go our way and then they go down the other end and score the third.
“But we kept fighting and everyone knows we don’t give up.
“At 3-1 it looks like they bossed us, but it wasn’t that way definitely.”
