Sir Alex Ferguson has launched the first volley of fire across Manchester City's bows by condemning the "kamikaze" spending in the transfer market.
Holding court at Old Trafford, barely an hour after City had unveiled their most recent big-money purchase, Mario Balotelli, and confirmation of James Milner's arrival for a medical had been received, Ferguson let fly but did not mention City by name.
"Over the last two or three years we have seen very wealthy owners become part of football clubs and therefore go on this kamikaze effort to spend their money," he said.
"It is amazing the amounts of money that are being bandied about in the present day game.
"Some people may think it could be dangerous. But if they have that kind of money, they are certainly using it.
"I don't see it abating. The kind of spending we are seeing at the moment will be here for two or three years, until such time as they understand you can't necessarily achieve all the time by spending."
