Domingo will join 88-year-old former US secretary of state Henry Kissinger and ex-Holland international Johann Cruyff as FIFA's advisers.

Blatter told CNN: "These gentlemen are more or less advisers, they are not the experts but advisers.

"They should be a kind of 'council of wisdom' which my executive committee would not like because they think they are the council of wisdom!

"I have also contacted the Spanish singer... Placido Domingo - he is happy, he is proud that he is part, and Kissinger also. People say he is an old man, but he is a wise man."
