Lin Jarvis, the managing director of the factory Yamaha team, has admitted that it will be a tough challenge for the team to secure all three MotoGP titles for a third successive season in 2010.
Valentino Rossi secured another riders title in 2009 after seeing off the challenge of team-mate Jorge Lorenzo while Yamaha also secured both the constructors' and teams' championships ahead of Honda.
Those successes allowed Yamaha to match its trophy haul from the 2008 season and while Jarvis admits that his team has the quality to fight for a hat-trick again next year, he conceded that rival outfits will also be right in contention.
“Everything is possible,” he told the official MotoGP website. “I think we have super riders, a great team and good engineers, so we have all the tools. But of course, our competitors are attacking from every side and when you are the leader, you can only be attacked.
“It's not easy to do it again, but we'll certainly give our maximum effort and I think we have all the ingredients.”
Jarvis added that he felt that there was four riders in particular who could be expected to fight for the title next year, including his own pairing, after the dramatic 2009 battle.
“One rider didn't totally dominate the  championship,” he said. “It was very close and very tense, but Valentino made fewer mistakes and had many victories, so he did a great job.
“Jorge made good progress as well, but lets see what next year will bring because Casey Stoner has shown how fast he is and Dani Pedrosa has again showed what he is capable of. The top four are a cut above the rest I would say, and next year will be hard.”
