UEFA president Michel Platini is still concerned over the amounts of money changing hands in the transfer market this summer. The Frenchman told L'Equipe: "Ronaldo's transfer stood out for me, but if Real have guarantees from the banks... On a personal note, I don't understand how anyone can spend 90million (euros) on a player. I'm embarrassed.

"But I remember the Maradona transfer from Barcelona to Napoli (in 1984). This would be the equivalent of 6.5 million and I found that vulgar. I think there is something wrong there.

"I don't like that, and even less given the fact that today players sign contracts only to then go and break them. But, as I said, if clubs have the money, what can I do?"

Platini last month described Madrid's £80million swoop for Ronaldo, which came just days after the £56million signing of Kaka from AC Milan, as "excessive" and revealed UEFA considered ongoing talks with clubs in a bid to establish a new set of financial rules their "top priority".

"We will do something," he said. "We are working on that. But it will take a little time. Perhaps two or three years. I want to establish rules."
