If this is Arsenal without Alexis Sanchez and Mesut Ozil, their fans ought to be very worried about the future indeed.Bournemouth came from behind to beat the Gunners 2-1 at the Vitality Stadium, courtesy of goals from Callum Wilson and Jordan Ibe after Hector Bellerin had put the visitors in front.Sanchez's absence from the squad had dominated the headlines before the game - the Chilean may have played his last game for the club according to several reports - and that summed up what turned out to be another dismal day for Arsene Wenger.The Cherries had just 41% possession but still had more shots on target - and the only stat that really matters, of course, is that they scored two to Arsenal's one.So, where did it all go wrong? 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.And for the first, many fans will have been scratching their heads wondering what Petr Cech was doing coming so far off his line to try and take the ball.That strike came with just 20 minutes to go and while it stunned Arsenal, in many ways this result was just too predictable given how many points they tend to drop on the road.However, one man who didn't foresee Eddie Howe's men getting back into the game was Alan Smith.

Smith's commentary 

The former Arsenal striker and Sky Sports commentator was being ridiculed for his take on the game just as Wilson found the back of the net:

"You can see Arsenal picking them off with a second," Smith noted, just as the Gunners' afternoon imploded.

Glorious stuff, unless you're an Arsenal fan, in which case it's another symptom of just how quickly they threw three points away.

Twitter reacts 

Several people picked up on it straight away:

The result means Arsenal have now won just two of their last nine league games and have suffered back-to-back defeats following last weekend's shock defeat at Nottingham Forest.

Admittedly, Wenger fielded their youngest team in the league for five years but that will come as little consolation - especially if Sanchez is on his way out of the Emirates.

Here we are in a New Year, but it's same old Arsenal.
