"It's very frustrating and very disappointing result for us, especially when you are 1-0 up and we made mistakes in areas where you wonder where they come from".
Hector Bellerin opened the scoring for the visitors in the 52nd minute, capitalizing on a brilliant slide-rule pass from Alex Iwobi.
"I still don't know what is going to happen".
Despite dictating much of the early possession Arsenal clearly missed their more illustrious attacking talents with Alexandre Lacazette cutting a lonely figure without the cutting edge of Sanchez and the injured Mesut Ozil.
The win saw Bournemouth climb to thirteenth on the Premier League table with 24 points.
Arsenal with 39 points - five behind rivals Tottenham Hotspur in fifth.
Even the 68th minute dismissal of Leicester defender Ben Chilwell for two bookings in quick succession couldn't lift lethargic Chelsea, which was outplayed in the first half and couldn't make its numerical advantage count at the end of the second period. Knocked out in the FA Cup third round, out of the top four in the league, and their best player in Sanchez leaving - Wenger has a massive job on his hand if he is to somehow rescue something from this season. Both of the hosts' goals came from some pretty suspect defending, with Rob Holding and Granit Xhaka failing to keep Bournemouth at bay for the second.
Here we are in a New Year, but it's same old Arsenal.
"They were focused and the attitude is one thing, but at that level it is a combination of quality and attitude, and today I question more the quality of what we have created, than the attitude of the players".
