Jorge Lorenzo wasn't happy with some of the strong moves made by his team-mate Valentino Rossi, during their thrilling battle for third in the closing stages of Sunday's Japanese Grand Prix.
Whilst many in the Yamaha pits might have preferred Rossi to give Lorenzo a little extra space, given he is firmly on course for the 2010 championship, the pair instead battled as if they were title rivals.
Although they had swapped places earlier in the race, the real action between them kicked off on the penultimate lap - when Lorenzo passed Rossi on entry to the first underpass, only for Rossi to slice back ahead of him on the exit, making possible contact.
Lorenzo then successfully lunged for the inside at a following left hander, but Rossi immediately barged back up the inside on the next right - the pair bumping fairings in the process.
Rossi guarded the entry to the underpass corner more carefully on the last lap, but Lorenzo still found a way around him soon after.
Once again, Rossi instantly responded, parking his M1 on the apex of a slow left corner in what proved to be the decisive pass.
"This was a big battle between Valentino and I, two warriors with the killer instinct," said Lorenzo.
"I have to say that at some points I do not think he was completely fair, we were both on the limit but some of his moves were maybe a bit too much and he touched me and pushed me wide when I don't think it was right.
"We are team-mates, I am fighting for the Riders' Championship but we are both fighting for the Teams' and Manufacturers' Championship as well and we have to remember this."
In an interview with MotoGP.com, Lorenzo gave stronger comments.
"The show is great for the business of motorcycle racing," Lorenzo said. "But when you are a rider and on a MotoGP bike reaching 300km/h on the straight and 180-200km/h on the corners, and you are feel the other rider touch you. It is not a good feeling. You know you are putting your life at risk.
