May 10 (GMM) 1964 world champion John Surtees can imagine Fernando Alonso soaring to a third drivers' title some time in the future.

The 73-year-old Briton, however - who won his title with Ferrari - doubts that the Spaniard can recreate his successes at Renault, where he won the world championships in 2005 and 2006.

"I think he will be champion again, but I do not know when," Surtees said in an interview with the Spanish newspaper Marca.

"And not with Renault," he added, referring to the 26-year-old's current team.

The Marca reporter asked Surtees if he thinks the next race Alonso wins will be at the wheel of a Maranello-built Ferrari.

"And why not BMW?" the Briton smiled.
