Sauber has confirmed Raikkonen for the 2019 season but the Finn wrote on his official Instagram account that it was a two-year deal.
He wrote: “Guess who’s back?! Next two years with @sauberf1team ahead! Feels extremely good to go back where it all began!”
Though the 2007 world champion has not won a race since 2013, and has not tasted victory in his second spell with Ferrari, he represents a major coup for Sauber.
