Former Barcelona star Rivaldo has insisted that agents are "dreaming" about the prospect of Lionel Messi linking up with Cristiano Ronaldo at Juventus.

Messi's future at Camp Nou has been called into question in recent days amid suggestions that he has informed Barca he will not stay on beyond next year.

A number of heavyweight clubs across the world are reportedly monitoring his situation, with Juventus among those said to be interested should he indeed leave Catalonia in the next 12 months.

Rivaldo believes that a move to the Allianz Arena, where Messi would team up with fellow superstar Ronaldo, would have a big impact on future transfer windows.

"With all this speculation, I believe that some agents are already dreaming about a Messi-Ronaldo double at Juventus and how big it will be around the globe," he told Betfair.

"If that happened there would be a world 'boom', and I believe Juventus would quickly recover any investment on the Argentinian thanks to the boost they would get from visibility and marketing.

"It would be historical to see both playing together and I'm sure many Juve sponsors would love to help financially, so, it's also a possibility for Messi. If there are rumours about his exit, then of course every club will be thinking about how they can sign him.

"That said, the two best players in the world for the past 10 years playing at the same club would be massive."

Messi has spent his entire career at Barcelona and racked up his 700th career goal for club and country earlier this week.
