and on the leaders.Wenger - who cancelled Monday morning's scheduled pre-match press conference - has been left puzzled by his side once again failing to turn up in a big game; Arsenal found themselves 3-0 down by 17 minutes, and played out the rest of the match with 10 men following the sending-off of defender Kieran Gibbs in a case of mistaken identity, which is expected to be overturned by the Football Association
Arteta accepts the Gunners were "just not good enough" and have no option but to raise performance levels against the Swans, with the squad having held a debrief session at their London Colney training base on Sunday
"We paid for our own mistakes
We have to take it on the chin because it is unacceptable to lose another big game like this," the Spaniard said to Arsenal Media
"You cannot only just move on, you have to analyse what you have done and react
I am expecting a big reaction on Tuesday (because) Saturday was not good enough for this football club
"The good thing is we have a lot of things to play for and we have always reacted to disappointments and difficult moments, but this one is a really hard one to take, it was a massive game for us and for me it is unacceptable.
"The pressure we put on ourselves by losing games like that is massive and there is no need for it
"We just disrupted the good season we were having
I don't know what else to say apart from sorry to everyone at the club, the fans, and we promise that we will try hard to put that right."
Arsenal are hoping defender Laurent Koscielny will shake off a calf problem which saw him replaced at half-time to be fit to play on Tuesday
The club are also understood to be set to appeal against Gibbs' dismissal by referee Andre Marriner, for which the official quickly apologised on Saturday after the match
The suspension would instead be transferred to Alex Oxlade-Chamberlain, who had committed the handball and indeed admitted his guilt at the time but was waved away
However, Arsenal may then also move to have that red card downgraded, claiming the midfielder had not in fact technically prevented a clear goalscoring opportunity as the shot from Chelsea's Eden Hazard looked to be going just wide
Wenger later confirmed on the club's official website, www.arsenal.com, that defender Koscielny would miss out on Tuesday night
Captain Thomas Vermaelen is likely to play at centre-half alongside Per Mertesacker, while 19-year-old Spaniard Hector Bellerin, who was on loan at Watford, has been drafted into the squad as cover.
"We have lost Laurent Koscielny for Tuesday's game with a calf problem
I don't know how long he will be out for
He has a scan today [Monday]
Everyone else should be available," Wenger said
The Gunners boss was also hopeful of having both Gibbs and Oxlade-Chamberlain available against Swansea
"There is a question mark about Chamberlain
The situation over his suspension will be decided today
After that I will make a decision
At the moment he is in the squad
We expected Kieran Gibbs' suspension to be overturned," Wenger said
Swansea head coach Garry Monk is under no illusions about what awaits his team
Wenger's side have little more than 72 hours to pick themselves up from that crushing defeat before facing a Swansea outfit that beat them at The Emirates last season.
A Michu double ensured a stunning win for the Swans in north London 15 months ago, but they will arrive this time around just four points above the relegation zone.
"We are expecting a reaction from them," Monk said
"That's the message to my boys.
"We will try to go up there with the right attitude and put on the right performance to come away with something."
Reflecting on events at Stamford Bridge when 10-man Arsenal were blitzed by Jose Mourinho's men, Monk added: "You can never see that sort of result coming, but obviously circumstances and stuff dictated the final scoreline.
"In terms of that game, I don't think you can really delve too far into it because of the circumstances that happened.
"The sending off changed that game, but Chelsea are a very good team
It was two powerhouses in this league, but Chelsea had the upper hand on the day.
"It is a horrible feeling whenever you lose a game, but to lose by such a wide margin is always hard to take."
