Valentino Rossi is no saint. Just ask Max Biaggi, Sete Gibernau, Marc Marquez, or even his current team-mate at Yamaha Jorge Lorenzo. Behind the happy-go-lucky demeanour that makes Rossi so popular, there is the mean streak every top sportsman needs to gain the edge at the very pinnacle.
But where is the line, and how often has he crossed it? All four of the rivals named above have called the MotoGP legend out for going too far in the past, with Lorenzo the most recent to do so following the San Marino Grand Prix at Misano.
Rossi's wars with Biaggi escalated to the point of scraps breaking out behind the podium, the short period where Gibernau was too big a thorn in his side effectively ended with their clash at the final corner at Jerez in 2005, while the Marquez feud arguably cost Rossi the '15 world championship.
