Max Verstappen says no doors have been closed by Ferrari announcing a new three-year deal with Sebastian Vettel over the Belgian Grand Prix weekend.
The 19-year-old is contracted to Red Bull until the end of 2019, but that has not stopped speculation linking him to a move to Maranello at an earlier date. Verstappen's recent frustrations with Red Bull's reliability has helped build a foundation for those rumours, but Vettel's new deal -- combined with Kimi Raikkonen remaining on a one-year contract for 2018 -- hints at Ferrari's commitment to the German as its lead driver until at least 2020.
