London - Carlos Sainz has once again played down suggestions he might complete a shock switch to the works Renault team for 2017.
The Spaniard has already been signed up for next year by Toro Rosso owner Red Bull, but there are rumours the energy drink company might negotiate a trade deal in exchange for cheaper customer engines from its French supplier.
Rumours and sport are false
Sainz said: "It's false," when asked by Vogue Espana if the rumours of a swap deal with Renault are true.
"I am mentored by Red Bull and Toro Rosso is their second team. So if they don't want me to go, I will not go."

Sainz, 22, also said that his only friend in the Formula 1 paddock is mentor and countryman Fernando Alonso.
"Apart from him, no," he insisted.
"There are people who you get along with better or worse, but being friends is difficult. It is a very false sport and although you have to get along with everyone, mixing friends with work is not good."
