Arsenal boss Arsene Wenger has hit back at his side's critics, including former player Paul Merson, following their draw against Anderlecht in the Champions League.

The Gunners surrendered a three-goal lead against the Belgian side at the Emirates Stadium in midweek as they were forced to settle for a point in their clash.

Critics lambasted Wenger and his side, with Merson claiming that the Frenchman and his team were "tactically clueless", but the 65-year-old is adamant that he isn't bothered about outside opinions.

Wenger told reporters: "Regardless of the score you have to play the right way: you have to defend well and attack well. Why should you stop playing one aspect of the game?

"These debates that I hear are a joke, a farce. People who have managed altogether zero games, they teach everybody how you should behave. It's a farce. If I really cared, do you think I would have survived for 18 years?

"What I care about is if players are punished or criticised in an unjustified way. Honestly, I cannot even be upset about it. It does not matter to me. You say what you want. You are free. I managed Paul Merson... I tried. I'm not interested in him."

Arsenal face Swansea City at the Liberty Stadium in their Premier League clash later today.
