Carlos Sainz is refusing to reveal any details concerning his future in Formula 1, amid reports he will join Renault as early as Malaysia.

The Spaniard, who sits ninth in the drivers’ championship, is believed to have signed a deal with Renault for next season to replace the underperforming Jolyon Palmer.

Earlier this year, Sainz admitted a fourth term with Toro Rosso would be ‘unlikely’, causing a uneasy relationship with the drinks company over his long-term future.

The deal is understood to be part of a merry-go-round between McLaren and Toro Rosso, with both outfits switching engine suppliers for 2018, thus allowing Sainz to be brought out of his Red Bull deal early.

Rumours suggest he could be driving for the Enstone-based squad in next months Malaysia Grand Prix, but the 23-year-old is giving nothing away on the potential move.

“Red Bull does its best for my career and so whatever they decide, I will accept it,” Sainz told Marca.

“It is difficult for me because what I say may please one person and displease another, so I prefer to say nothing.

“All I know is that there are many people in Toro Rosso that I want to thank for making me the driver I am today.”
