Former Arsenal defender Sol Campbell has insisted that Arsene Wenger is the right man to manage the club.
The Frenchman has received significant criticism as a result of the Gunners' form so far this season, including their shock Capital One Cup defeat at the hands of League Two minnows Bradford City.
Despite the abuse, Campbell believes that Wenger is right for Arsenal but that he must change his ways in some areas of the game.
"He is the right man for the job, but he has to realise that the playing landscape has changed and the market has changed," Campbell told BBC Sport.
"You've got to sometimes take a risk. Taking a punt on a player 10 years ago for £500,000 might now be £7m. You can't always get these £500,000 players, turn them into great players and sell them for £20m.
"Seven years plus without a trophy for Arsenal is too long. Arsene would be the first to say that. Why not wait until January and just go for it?"
Arsenal travel to Wigan Athletic on Saturday in the Premier League.
