Cape Town - Despite retiring at the end of last season, Toto Wolff believes Nico Rosberg could one day be back in F1 "in a Ferrari or somewhere else."
Rosberg announced that he was quitting Formula 1 just five days after winning the 2016 Drivers' title.
His decision came as a shock to many and while Rosberg has insisted on several occasions that he made the right decision, his former boss reckons he could yet be back in the paddock.
"I think when he took the decision to retire it was because it was just too much," he said.
"It was a very stressful year against probably the best driver in F1 and he felt, at that stage, exhausted. That is how he appeared to me.
"But he is 31 years old. If he is unlucky, he has another 70 years to go in his life!
"I wouldn't be surprised if he changes his mind in a year and reappears in a Ferrari! Or somewhere else."
