Sakon Yamamoto will return to the Hispania line-up for his home round of the F1 season in Japan after Christian Klien
reiterated that his outing in Singapore is currently a one-off.
Klien made his return to an F1 race seat for the annual night race after Yamamoto was ruled out by food poisoning on the eve of the event, meaning the F1 newcomers have now used all four drivers on its books this season.
Although happy with his performance prior to being forced to retire from the race, Klien has admitted he is unsure if he will get the chance to race again before the season comes to a close with Yamamoto set to be back for the next round of the year at Suzuka.
“I cannot say if I will drive again this year,” he told F1Pulse.com
, “but for Japan it will definitely be Sakon in the car. Obviously, the performance (in Singapore) was pretty good. Maybe the team will make another decision towards the end of the season but I have no idea at the moment. Perhaps I will return, I don't know.
“We are checking the possibility with teams who have a seat left for next year. The whole weekend in the car helped to show (my performance) to get a better chance for next year to get a drive.”
Speculation during the weekend had suggested that Yamamoto's 'illness' wasn't the real reason why he failed to race on the Singapore streets, but Klien insisted that as far as he was aware, there was a genuine reason why the Japanese driver hadn't competed.
“They had called me on Thursday night stating that he had food poisoning or whatever, so he didn't feel well,” he said. “So I got into the car. That's all I know. I was pretty happy about that, so I concentrated on the race weekend. He was at the track on Saturday as he felt better.”
