“Nobody knows how competitive Valentino will be from the start. Jorge has two more years under his belt and is very fast and consistent. Dani is riding superbly. Unfortunately Casey won't be there, but there are a lot of young fast riders.
“My opinion is that Valentino can definitely win races in the first season. Can he win a tenth grand prix championship? I don't know. Time will tell.”
Rossi won four of his seven premier-class titles and a symbolic 46 race wins for Yamaha.
