Nico Rosberg messaged Merceds team-mate Lewis Hamilton to inform him of his decision to retire from Formula One before making the announcement public.

The new Formula One world champion surprisingly revealed >he was to call it quits  on Friday, just five days after >clinching a maiden title ahead of Hamilton at the season-ending Grand Prix in Abu Dhabi.

The two have seen their childhood friendship tested by a fierce battle for supremacy in F1 in recent years and Rosberg admitted before the final race that >it was difficult for them to have a close relationship .

However, Rosberg says that he ensured Hamilton knew of his retirement plans out of respect. "I informed Lewis myself because it's the right way to do it," he said at the FIA Prize Giving in Vienna.

"We've had such a battle and so many moments fighting each other so I thought it was correct to let him know of my decision. I had to do it a bit quick, so I sent Lewis a message. Maybe we'll have a discussion about it [in person]. It has been so short notice because the priority was to let the team know as quickly as possible so that was a bit of a compromise for me, that I wasn't able to do a perfect job in taking enough time to notify everybody that was close to me."

Rosberg competed in 206 Grands Prix events during his career, winning 23 races and standing on the podium 57 times.

And the German insists there is no chance of him reversing his decision. He added: "Definitely not. [I am] finished. Done. End of story."
