It's becoming more and more difficult to imagine Arsene Wenger digging his way out of this one.

Arsenal travelled to West Brom on Saturday and fell to the Baggies at The Hawthorns in an embarrassing 3-1 defeat. The Gunners defended listlessly and completely shut down on set pieces, allowing two West Brom goals from corner kicks.

And the loss is no aberration. Arsenal has been absolute terrible the past few months. On top of a pair of 5-1 drubbings at the hands of Bayern Munich that jettisoned the Gunners from the Champions League, they have lost four of their past five Premier League matches. The two games Arsenal have managed to win in the past month were both against non-league sides.

The match's first goal came in just the 12th minute, and served a sign of the dismal day to come for Arsenal. Off a Nacer Chadli corner, West Brom's Craig Dawson flicked a header past keeper Petr Cech to take the early 1-0 lead.

But Arsenal did have its moments, and an opportunity to stay in the match. Three minutes after the opener, Alexis Sanchez equalized on a fine goal. A ball over the top left him fairly isolated on the left of the box. He played it off his chest, side-stepped a defender, and fired a goal into the roof of the net.

The game still looked very much within Arsenal's grasp at that point. But Cech suffered a knock toward the end of the first half, forcing him off in favor of David Ospina. And Ospina, a much more error prone keeper than Cech, didn't step up to the challenge.

A strange sequence gave West Brom the lead once again. In the 55th minute, Chadli lofted a ball over the defense. Ospina charged on the ball but didn't claim it, allowing Hal Robson-Kanu to put a boot on it and send the ball rolling into the net. Arsenal protested because the ball rolled through the legs of an offside West Brom player, but since he never touched it, the goal stood.

The third and final goal came from some more nightmare defending on a corner. And once again, it was Dawson who rose for the goal. But had he not scored, one of two other Baggies in the area would've. Arsenal's defense had inexplicably shaded to one side of the box, leaving multiple attackers open on goal. It's mental errors like that that have put Arsenal in its slump.

It should be noted that while this is a game that Arsenal should have won, West Brom are no slouches fighting off relegation. Tony Pulis has his Baggies in eighth place, fighting for a Europa League spot. And Pulis specializes in wins like the one on Saturday: shut down the opposing offense and nick some goals from set pieces. Of course, that's no excuse for Wenger, who has faced Pulis dozens of times and knows exactly what will be thrown at him.

It's unclear how much longer Wenger can sustain these poor results and hold on to his position in North London as protests for his ouster continue among some Arsenal supporters.

I still think Wenger will not be fired, although he may not be given a new contract. He'll see out the season, which means he'll be fighting for a top four spot the whole time in hopes of winning back some job security. Arsenal is currently in fifth, five points off Liverpool in fourth.

But the uncertainty surrounding Wenger has spread throughout the squad. The club's top two players, Mesut Ozil and Sanchez, are both due contract extensions. Players want to know who they're going to play for. So until we have a clear answer to the Wenger situation, we won't have answers in the Sanchez or Ozil ones.

If Arsenal keeps losing and the downward spiral continues, it would come as no surprise to see a wildly different Arsenal side next season, both on the pitch and the touchline.
