Real Madrid, Chelsea and Manchester City are on red alert over the new availability of AC Milan superstar Kaka. Gazzetta dello Sport says Milan patron Silvio Berlusconi is reigning in spending and planning to introduce a new salary cap from the start of next season.

Kaka is Milan's highest wage earner at £7.5 million-a-year, but can expect much more at any one of Real Madrid, Chelsea or Manchester City. With Milan also battling to qualify for next season's Champions League, that could also become a factor in the Brazilian's thinking this summer.
