Manchester City boss Roberto Mancini says he needs to break the bank to improve his squad.

Mancini, who has spent over £200m since succeeding Mark Hughes three seasons ago, says new rules should be introduced instead to stop clubs like his from getting ripped off.

The Italian - whose side travel to Southampton today - is keen to land Napoli hitman Edinson Cavani in the summer, but might have to shell out almost £60m to get his man.

"In football, if you work well, you can find good players without spending maybe £30m on one player," he said.

"But when City move for a player, if his value is £10m, they ask £30m. There should be other rules for this."
