Palermo president Maurizio Zamparini insists the Premiership and Spanish Liga will soon both collapse due to their clubs' spending.

When asked why Liga and Premiership teams do so well in the Champions and Europa League, Zamparini said the bubble would soon burst.

"They dominate and win precisely because they have no rules. The Spanish can afford to take Kaka and Zlatan Ibrahimovic away because they pay 3-4 million Euros more in wages and 60-70 million more for the transfer.

"In my view they are the crazy ones and we should not follow their example. Sooner or later the English and Spanish clubs will fail."

Nonetheless, Zamparini feels more can be done to make the Serie A clubs more competitive.

"First of all we need to reduce Italian tax rates to the level of the other European countries.

"Then Europe should set salary caps, although I realise that is a very difficult thing to achieve. I'd do it tomorrow."
