Although Rossi has fewer wins than his teammate Jorge Lorenzo - four to six - it is the Italian who has been the more consistent rider.
Rossi has taken 13 podiums. The only race he has not finished inside the top-three was San Marino, while Lorenzo has just eight to his tally.
As a result it is the 36-year-old who is leading the charge on 263 points, 14 ahead of his Yamaha teammate.
And although momentum has swung between the two challengers of late, Suppo feels that Rossi is fated to win the title as Marc Marquez was in 2013.
