Arsène Wenger insists that managers must help their clubs in these tough financial times.

The Arsenal boss is renowned for his ability to spot a bargain in the transfer market and has made hefty profits on a number of deals during 13 years in north London.

And Wenger believes that managers who make unreasonable demands of their chairmen should be more sensible, especially in the current economic climate.

"Of course," said the Frenchman. "That's why you know I always try to earn my wages. When I want them paid, I try to get that money back to make it for the Club.

"It depends on the model you have. When you have an income, a yearly income, you say to yourself: 'How much can we spend on wages?' Is it 50 per cent, 55, 60? For some clubs, 70.

"But when you know it's 70, or 50, you don't go higher than that [with what you spend]."
