SINGAPORE - This weekend's Singapore Grand Prix might be Carlos Sainz's last race in a Scuderia Toro Rosso car.

Media reports have said that he has secured a transfer to Renault, which could see the 23-year-old Spaniard start for his new team as soon as the Malaysian Grand Prix in Sepang on Oct 1.

But Sainz remained tight-lipped about his likely move.

When queried about it at an event held at Acronis' international headquarters at Suntec City on Wednesday (Sept 13) night, he said: "I know there's a lot of rumours that have been going on around, a lot of things been said. But for me, I prefer to focus on this weekend.

"I come here motivated as a Toro Rosso driver to score as many points as possible."

Sainz has been linked with a possible switch to Renault as part of a complex merry-go-round that could involve Toro Rosso using Honda's engines, and McLaren ditching Honda for Renault's power.

Daniil Kvyat was glad to stay away from all the distracting rumours revolving around his team-mate.

He joked: "It's perfect for me, I don't have to answer any stupid questions."

When asked about how he felt going into what could be their last race as team-mates, he added, with a bit of sarcastic laughter: "Very sad, (you would) see my tears."

"Whatever happens, sooner or later at some point, you might see us again together. Throughout our careers, at some point, we had always cross paths.

"I hope that's going to be the case. But I don't know what's going to happen, it's his future, not mine."
