Arsenal boss Arsene Wenger insists the big-spending of Manchester City and Chelsea cannot be sustained.

"Football will not survive a long time with the way it is ruled now," said Wenger. "You cannot have a world where there is suddenly an influx of money, it puts everybody else under pressure to pay twice as much.

"Somebody with unlimited resources can strain the whole world. This is not an anti-Man City case. But can our world go on like that? It puts inflationary pressure on people who cannot compete."
