Wenger's squad have endured the worst start to a season under the Frenchman, who on Tuesday received the full backing of chief executive Ivan Gazidis in the wake of an appalling run of results and Saturday's 4-3 capitulation at struggling Blackburn.
The misery around the Emirates Stadium, with an official attendance of just over 46,500, deepened when James Collins headed the League Two side ahead on 16 minutes. However, Kieran Gibbs levelled before the break with his first senior goal before Alex Oxlade-Chamberlain fired in a 25-yard effort on the hour and Yossi Benayoun wrapped things up late on.
Despite the criticism, Wenger has no intentions of letting anything deflect him from his job. Asked if he should consider bringing in a defensive expert - such as former player Martin Keown - to help shore up the backline, the Arsenal manager responded: "I have just completed 30 years of coaching. I don't want to answer this kind of question."
On his 'vote of confidence' from the board, Wenger continued: "I am not bothered at all by this speculation. I am completely focused on doing well. I can understand that people are unhappy and criticise, but you know as well as I know people are very quick to go overboard.
"I accept critics and I do not say it doesn't matter that people criticise us, and like anybody else, I prefer it when they say I am good.
"When we do well we take all the plaudits, so we have to take as well all the blame when it doesn't go as well - but we have as well on both sides to take some distance."
