Two poor away results in the Premier League appears to have instigated this decision, after losses away at Everton and Manchester City.
Many Arsenal fans feel their Premier League title hopes are already over, having lead at both Goodison Park and the Etihad, before losing both matches 2-1.
Cancelled by Cech & Koscielny
Daily Mirror journalist John Cross, who has long established good sources at Arsenal, reports that Gunners first team players cancelled their own Christmas fancy dress party.
Cross writes: “Senior players, like Petr Cech and captain Laurent Koscielny, were concerned about the message it would send if they were pictured partying in comedy costumes.”
Some players went out for a meal, according to Cross, but it was a constrained affair and there was no dressing up.
The only Christmas party attended by most Arsenal players this week was the one with the Junior Gunners, that Alexis Sanchez appeared to enjoy so much.
