Nico Rosberg's return to the Formula One scene after his retirement has confused Kimi Raikkonen, the Finn has admitted. 

German Rosberg announced his retirement after winning the drivers' championship in 2016, but in the two years since he has appeared as a pundit for Sky Sports' race coverage, both in England and Germany.

However, while Raikkonen respected Rosberg's decision at the time, he is unsure why a return to Formula One as a pundit was necessary. 

Rosberg's championship win, where he overcame both Sebastian Vettel and Lewis Hamilton to storm to victory, came days before he announced his retirement from the sport, in a surprise twist.

But his return doesn't sit well with Raikkonen, who has just released his new autobiography, titled ‘The Unknown Kimi Raikkonen’.

“When he explained why [he is stopping] I thought it was cool and I understood,” Raikkonen said, per Planet F1.

“Now he’s standing there with a microphone. I cannot understand why given the reasons he gave for wanting to leave.”

Now aged 38, Raikkonen is considering his own future in Formula One, with his current Ferrari contract set to expire at the end of the year and rumours he could be replaced by Charles Leclerc.

However, he doesn't see himself following in Rosberg's footsteps into any role within the media once his own career comes to an end. 

“No it will not be hard to stop this job. I will be relieved when all of the things not involving driving will end. The driving is great but nothing else."

"I’m interested in doing something like developing a car, but in the background not in public. It will not be standing with a microphone,” Raikkonen insisted.
