Kaka hails Ronaldo

Cristiano Ronaldo and AC Milan's Kaka will be vying for the Ballon d'Or award next month, but the Brazilian ace believes there should be only one winner.

Ronaldo was exceptional for the Reds last season, helping to inspire United to the league title and a semi final spot in the Champions League. But Kaka, whose Milan team defeated United in the last four and went on to win the tournament, was voted UEFA Footballer of the Year for 2006/07.

With the prestigious Ballon d'Or award to be announced on 2 December by France Football magazine, Kaka has singled Ronaldo out for special praise.

“I would vote for Cristiano Ronaldo as the best in the world,” he told Italian reporters. "Not just for his quality, but also as he has been able to do so well with Portugal. Lionel Messi is also a great player, but he has not won any titles this year."

Sir Alex Ferguson clearly agrees with Kaka's assessment. "The season Ronaldo had last time around was unbelievable stuff," he told Inside United.

The Ballon d'Or award has this year has been extended to the best players in world football, which is why Carlos Tevez was among a handful of non-Europeans to make the 50-player shortlist.
