Manchester United manager Sir Alex Ferguson has hit out at the "kamikaze" spending which has occurred in the Premier League in recent years.
Ferguson has revealed his amazement at the transfer market following a summer where neighbours Manchester City are poised to take their spending past the £125million mark.
England midfielder James Milner is poised to join from Aston Villa for a fee of around £30million.
City have already landed Mario Balotelli, Yaya Toure, David Silva, Aleksandar Kolarov and Jerome Boateng during a record-breaking summer.
"It's amazing the amount of money that is being bandied about," said Ferguson, who declined to mention the clubs in question 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.
"Some people may think it could be dangerous and 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."
