Madrid completed the world-record signing of Kaka from AC Milan overnight, splashing out a reported 65 million euros (£59million) for the Brazil playmaker.

Speculation is also rife that they could are set to beat even that with an 80 million euro (£69million) bid for Cristiano Ronaldo, and Laporta believes that could be dangerous for football.

"It's an opportunity to try to show that the market is at different levels," he said. "To pay these quantities is exorbitant.

"It doesn't fit in with the reality of the market and it's too risky. It's distorting it."

Laporta insists Madrid's massive spending power does not worry him following a spectacular season for Barca which saw them lift the treble of the Primera Division, Copa del Rey and Champions League.

Barca have been linked to big-money deals of their own but their president claims he will not be following their bitter rivals' example.

He added: "We only have to make touch-ups. I'm trebly calm."
