Carlos Sainz has said Ferrari and Renault's rumoured interest in his services is "a compliment", but insists he is happy at Toro Rosso.
The Spaniard has been linked with moves to Ferrari, to replace the recently re-signed Kimi Raikkonen, and to Renault in place of rookie Jolyon Palmer.
"It's a compliment that Ferrari is interested, it's a compliment that Renault is interested," Sainz said. "At the end it's manufacturers, and at the end it's manufacturers that rule Formula One and they are here to stay."
"To get the interest from such an important manufacturer like Renault is of course. I feel a lot of pride for it and I am not going to deny it, it makes me feel happy."
However, despite being liked with manufacturer-backed teams, Sainz says he is happy at Toro Rosso, where he was recently confirmed for 2017.
"I am very comfortable in Toro Rosso, I have a lot of support from the big bosses, which is important for me to have the support Helmut Marko, Christian Horner and Franz Tost," he said. "They trust me a lot and it's the right place to be, the people trust you, you have James Key also in Toro Rosso, who, next year could surprise many people with the new regulations."
"I'm sure next year Toro Rosso is not a bad place to be and in any case it could be a good place also with the links with Red Bull and everything going on."
