Jul.28 (GMM) Sebastian Vettel could be ready to move on again after two years of racing with Red Bull beginning in 2009, according to his current team boss.

Toro Rosso co-owner Gerhard Berger, who is set to lose the highly rated 21-year-old German to the senior team at the end of this year, has suggested to the tabloid newspaper 'tz' that Vettel has penned a two-year deal with the outfit run by Christian Horner.

Horner confirmed on Monday that Vettel is a "long term" contract with the popular energy drink company, but it is also well-known that BMW has some sort of option to bring the team's former test driver back to Hinwil in the future.

And Berger says: "In 2011 Sebastian Vettel will be interesting not only for BMW, but also for Mercedes and Ferrari."
