Carlos Sainz was very close to making a deal to become a Renault driver, but Red Bull blocked the move and as a result the Spaniard will remain with Toro Rosso for another season.
His father, rally legend, also Carlos Sainz told Marca, "He was very close to leaving Toro Rosso. It was a was really interesting three year offer from Renault and he was interested. In the end Red Bull refused as they wanted him for one more year."
"Next year will be a good one for Red Bull and they want to have someone in case something happens, and they prefer that it is Carlos. So on one side that is good and on the other side it is not so good." mused Sainz senior.
"Joining a team like Renault is an important step but hopefully in the future something like that will happen. Red Bull has young drivers confirmed for the next three years and so the future there is a little difficult. Unless one of them is upset and leaves, it will be difficult to make the jump to Red Bull," added Sainz.
Red Bull team chief Christian Horner told media shortly after Sainz was confirmed for Toro Rosso, “He’s on a long term agreement with Red Bull, we’ve got him in the junior team, within Toro Rosso."
"At the moment you wouldn’t say being in a Renault was a better bet than being in a Toro Rosso, and we have immediate access to him should we need it.”
“So having invested in him, having funded him through his junior career, put him in the junior team now at Toro Rosso, it doesn’t make sense for us to release him to Renault,” added Horner.
