Nico Rosberg insists his decision to retire is final and will not seek a return to Formula 1 in the future, despite a suggestion from his former boss Toto Wolff.

The German, 31, shocked the F1 world with his announcement to retire just days after grabbing the world championship in Abu Dhabi last season, a title he worked so hard for years to achieve.

Nico made his first appearance at a Grand Prix since that moment in Monaco just over two weeks ago and speaking before Canada, Wolff stoked up the prospect of a future comeback.

"I would not be surprised to one day see Nico racing at Ferrari or someone else,” the Austrian claimed.

"He's only 31, he's still young. Perhaps he will change his mind."

However, Rosberg, who scored 23 wins and 57 podiums during his 10-year stint in the sport, appears unlikely to do so.

"No, I really have finished my career," he told Germany's Sport Bild.

"I am happy and proud of the results and the successes I have had. It fulfils me a lot but it's now in the past and I'm going to do new things.

"I've never thought about it [one-off return] but I'd probably say no," he added.

The German isn't just ruling out an F1 return but also claims he is not interested in any other motorsport series for now.

"At the moment no," Rosberg insisted when asked about any return to the racetrack.

"I am currently looking for other challenges. But who knows, maybe one day in the future."
