Sainz to drive with eye infection

Carlos Sainz Jr. still expects to drive this weekend in the Russian Grand Prix despite suffering with an eye infection.

Sainz didn't take part in Friday's first practice session due to the eye infection and was replaced by Artem Markelov, who could only drive to a P15 finish in Sochi.

The Spanish driver, who is moving to McLaren at the end of the season, says it is just his latest adventure in Russia. 

"It's funny, I've been evacuated by helicopter and this is one more experience," Sainz joked. 

Sainz also responded to Max Verstappen's claims that Honda will be quicker than Renault next season - with Red Bull switching engine providers at the start of the 2019 season.

"I think it's very difficult to use the word certain, as I'm not certain of anything in Formula One," Sainz explained. "But I still have faith in Renault. I'll use this engine next year and I think the work they are doing is enough."
