SPIELBERG, Austria -- Carlos Sainz says it is "unlikely" he will remain at Toro Rosso for the 2018 season if he is unable to move up to Red Bull.
Sainz is widely regarded to be one of the hottest commodities on the current grid but finds himself stuck in a third season at Toro Rosso. The Spaniard's route to the senior team appears to be blocked by Daniel Ricciardo and Max Verstappen, who Red Bull have locked in for at least 2018.
Impressive performances in 2016 saw him linked with Renault, rumours which have continued into this season.
