Former F1 driver Gerhard Berger believes that if Ferrari don't manage to keep Sebastian Vettel happy in the upcoming 2017 Formula One World Championship then the possibility of a switch to their rivals at Mercedes could be a very real possibility.
Speaking in the German press, Berger claims that no matter who Mercedes get to replace Rosberg for 2017, it will only be a one season deal as they attempt to lure a top driver for 2018 onwards and Vettel could very easily fit the bill.
While it seems as if Vettel is more than happy with Ferrari, another disastrous season for the Maranello based squad as Mercedes continue to dominate may be the only bait Vettel needs to jump ship…
"Suddenly Ferrari is feeling the pressure. Sebastian will closely monitor their progress and take his time in renewing his contract. I'm sure deep down he wants the chance to go with Mercedes in 2018," Berger told Bild. "So Ferrari need to try to keep Vettel happy, so they don't lose him."
