The manager has repeatedly had to defend the club's cost-consciousapproach while the trophy cabinet remains bare and has now said thereis no way out in the foreseeable future.
Crossroads: Debt goes one way, wages will go the other, says Arsene Wenger
Arsenal's move to Emirates Stadium has saddled them with a debt of £239 million and annual payments of £20m on a 'mortgage' which is not due to be paid off until 2031.
They are generating profits in other parts of the club's business but the problem is stretching an annual wage bill which had already reached £110.7m by the end of last season.
'Yes, the wage bill approach will stay the same until the stadium is paid off,' said Wenger. 'But when it is we can go a bit higher. We can never be dominant in the transfer market because it is never just the money you spend to buy players, it is the wages as well.'
They made £56m overall in the year to May and have cleared all debts unrelated to the stadium, but profits from the football operation are expected to drop.
So free signings, such as Marouane Chamakh, and the focus on youth are here to stay.
Wenger believes they will take what would be a 'significant' step forward by winning at Chelsea today and has urged his players to forget their neighbours' acknowledged superiority.
'I don't believe in history,' said Wenger, aware Arsenal have beaten Chelsea just twice in their last 15 meetings.
Wenger has just served a touchline ban but claims he was just unlucky to be caught.
'In the 14 years I have been here and walked up and down the corridors I have seen people who have lost it much more than that.
'It depends if you are caught on camera or not.'
So was Harry Redknapp right when he said the studious Arsenal boss has been driven nuts by life in the Premier League?
'Frankly, no,' said Wenger. 'I was already passionately crazy about football and that has not changed. All managers are mad.'
