Cardiff beckons for Gianluigi Buffon and an elusive Champions League winners' medal is not the only prestigious prize within the gangly reach of one of the great goalkeepers.

But the 2006 World Cup winner has never been one to let anything slip easily through his fingers.

His exemplary form this season has been a key reason for Juve's irresistible advance on the Welsh capital, where they will face Real Madrid or Atletico Madrid on June 3.

And if Buffon and co. do return from Wales victorious, what price the skipper crowning a silverware-sprinkled career by becoming the first goalkeeper since Lev Yashin in 1963 to win the Ballon d'Or?

With Real Madrid the more likely opponents, shutting out Cristiano Ronaldo would inevitably bolster Buffon's prospects of ending the Portuguese striker and Lionel Messi's recent monopoly on world football's leading individual award.

The notion that "Gigi" deserves nothing less is already being pushed noisily by the adoring Italian media.

But the well-travelled Claudio Ranieri, whose long career included a stint managing Buffon at Juventus, says the case for Buffon is founded on more than patriotic fervour.

- 'Done nothing yet' -

"If they win the Champions League I really think he would deserve it," the former Leicester and Chelsea boss told SkyItalia.

"It is a very particular role and it is not easy. They have only given it to a goalkeeper once, with Yashin. But if you ask, who is the best footballer in the world, then yes, the answer can be Buffon."

Juve booked their second final slot in three seasons on Tuesday by beating Monaco 2-1, completing an impressive 4-1 aggregate win in front of home supporters convinced this could be their year.
