When asked about the torturous transfer saga involving Cristiano Ronaldo, Manchester United and Real Madrid, Blatter insisted players should be allowed to play where they wanted and pinpointed a trend towards "slavery" in clubs' transfer dealings.

Ronaldo has now supported Blatter's stand, but refused to shed any more light on the proposed transfer.

"I agree with the comments of the president of FIFA. What he said is right," he told Portuguese channel TVI.

"At the moment there is no agreement with Real Madrid. We have to wait for the next few days to see, but I do not know where I will begin next season.

"This is all I have to say at the moment."
