Arsenal failed yet another of this season's big tests when they were beaten 2-0 at Chelsea on Sunday. Having lost to Manchester United the previous week, Tony Cascarino in the Times thinks it's question time for Le Professeur.

Arsène Wenger is a genius. He has few peers in either the modern or monochrome era. But I’m sorry, if Arsenal don’t go close to winning the Champions League this season, some serious questions must be asked about his future at the club. Really, it has become that bad.

This might sound like heresy, but where are Arsenal going? Out of both domestic cups, as good as out of the Premier League title race and perhaps, if they’re not careful, out of Europe soon, too. A fifth straight year without a trophy? For a club like Arsenal, that is heresy.

Watching their defeat by Chelsea at Stamford Bridge yesterday only reinforced a long-held feeling. Yes, Arsenal play the beautiful game, the five-yard passes, the intricate triangles. It’s great to watch. When they meet the lesser teams, they pass them to death.

When they meet the better teams, all that becomes so predictable. As is often the outcome: defeat. The word is out on Arsenal — press them, smother them, step on their dancing feet. And when you’ve done that, hit them on the break. Manchester United did it the previous weekend, Chelsea did it yesterday. It was like Groundhog Day.

The same is true of Wenger’s apparent obsession with small, nimble players, those who paint the pretty pictures yet have so little upper-body strength that, when challenged, they are brushed aside like annoying gnats.

Why, with no Robin van Persie, did Wenger not invest in a proper centre forward in the January transfer window? Eduardo da Silva is not right yet after injury, Nicklas Bendtner is just lazy. There are forwards out there — look at Harry Redknapp snapping up Eidur Gudjohnsen for Tottenham — and a quick fix, a short deal, would have been perfect for both parties.

No, Arsène kept his chequebook shut. He may regret that. The evidence is mounting against him, like never before in his 14 years in charge at Arsenal, and it is damning. He might run much of the show at the Emirates Stadium, quite understandably, but there must be someone in that boardroom who is getting twitchy.

Perhaps several people.

It's a similar story from Rob Kelly in the Daily Telegraph.

Following their 3-0 mauling at the hands of Chelsea in November, Arsene Wenger remarked that Didier Drogba “doesn’t do much”. This despite the Ivorian scoring twice, then his ninth and tenth goals in 11 matches against Wenger’s men. If Drogba really “doesn’t do much” in the eyes of the Frenchman, one shudders to think what his assessment of Gael Clichy, Manuel Almunia and Theo Walcott might be.

It is hard to fathom what Wenger felt he had to gain from his criticism of Drogba. All it was ever likely to do was spur the Ivorian on to greater deeds, and once again at Stamford Bridge on Sunday the Chelsea striker proved his credentials in emphatic manner. In the aftermath of Chelsea’s destruction of Arsenal in November, I argued that Drogba was the most complete striker in world football, and while Wayne Rooney has since kicked on to grab a share of the limelight, the Ivorian has arguably got a narrow edge on his rival.

How Wenger could do with a talismanic striker in the mould of Drogba or Rooney. In the absence of the injured Robin van Persie, Arsenal have looked desperately short up front, both figuratively and literally. While the muscular Drogba stands at 6ft 3in and acts as the focal point of the Chelsea attack, Arsenal had to make do with the impish Andrei Arshavin, all 5ft 7in of him.

Another trophyless season beckons for Arsenal, while Chelsea and Drogba look with relish towards a future laden with silverware. It is time for Wenger to act in the transfer market to plug the gaping holes in his talented squad.
