"But speaking to MCN shortly before Rossis return to Yamaha was confirmed in the short MotoGP summer break, Stoner said: I think he's eating enough humble pie at the moment.
"I just feel completely sorry for Ducat that he has gone there and done nothing but complain about the bike and obviously they now have a bike that can do well because he keeps getting beaten by Nicky and Hector (Barbera) and that is nothing to be proud of.
"We heard all this stuff about how he was going to lead Ducati to greatness and we haven't seen any results.
Rossis talent and renowned development skills were seen as the perfect combination to make the finicky Desmosedici a serious title contender again.
Yet in 27 appearances to date, Rossi has only been able to deliver two podium finishes and his humbling failure to get even remotely close to emulating Stoner has only enhanced the Australians reputation.
Stoner also relishes ramming taunts by Rossi and his legendary crew chief Jerry Burgess back down their throats.
Rossi and Burgess were both adamant they could fix Ducatis long-standing front-end issues that Stoner frequently complained about towards the end of his tenure on a factory Desmosedici.
And Rossi enraged Stoner towards the end of 2010 when he said it was impossible to gauge the performance of Ducati because the 26-year-old wasnt putting in maximum effort having already clinched a big money switch to Repsol Honda.
They ate their words from day one. Jerry saying that it would take him 80 seconds to fix that bike and that it was a simple issue and now they have had pretty much two years on the thing have not made any inroads.
"Valentino got his best result in the dry virtually in his first race on the Ducati supposedly with shoulder injuries and I haven't seen any improvement over the past two years and this is disappointing.
"I feel sorry for the people behind that bike. Valentino obviously doesn't want to push limits and ride a bike that is not perfect. He has admitted that. If he's had a bike that is that good in Yamaha before and hasn't had to push when the bike is not perfect then God knows how good that bike is.
"Obviously he doesn't want to put the effort in with Ducati. It is disappointing for them that they're doing all they can and he is not even trying to get the best out of it.
"There are certain riders in this paddock who have considered themselves test riders who can lead a manufacturer in the right direction and Valentino has certainly proved himself not to be the case with Ducati. It is just obvious that he needs an extremely good bike to be able to win.
"It is blatantly obvious that he can't win with a Ducati and make it competitive so he's looking for the first option out. He said he wanted to finish his career with them and now he wants to jump ship.
Stoner also mocked the lets stick together; slogan recently used by Rossi on his special AGV helmet used at his recent home race in Mugello.
"He should (stay with Ducati) when recently he was wearing "let's stick together" on his helmet.
Rossi reagierte via Twitter wie immer sehr elegant:
"sempre molto carino il mio amico Casey ah ah ah
"Casey ist immer so nett zu mir ....ahahahaha"
