The news Sebastian Vettel had chosen to re-sign for Ferrari was not a surprise. But the fact it was for three years, tying him to Ferrari until the end of 2020, certainly was.
Come the end of 2018, both Mercedes seats are potentially on offer, with Lewis Hamilton's deal having just one year remaining and the team yet to confirm who will be alongside him next year. Daniel Ricciardo's contract at Red Bull will be up too, while there will also be opportunities at McLaren and Renault.
Vettel reckons it was a "no-brainer" to stay with Ferrari. "We haven't yet achieved what we what we wanted to achieve but things are looking pretty good," he said.
