Sebastian Vettel's Brazilian Grand Prix victory proved just how strong Ferrari's 2017 challenger is, according to Scuderia team principal Maurizio Arrivabene.
Vettel made a fast start to jump polesitter Valtteri Bottas into the lead at Turn 1, a move that proved crucial to the race victory. Ferrari's strategy ensured the German retained his lead during the only pit stop phase, before he maintained his advantage to beat the Mercedes driver to the chequered flag.
In the post-race press conference Vettel admitted the win had come as a "great relief" for Ferrari after the Italian team missed out on a first world championship title in a decade to Mercedes.
