UEFA president Michel Platini is concerned about the amount of money being spent in transfer fees this summer.

The French legend told 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. 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?"
