Christian Klien on Friday said he is expecting to be back at the wheel of HRT’s F1 car in Valencia.

Although fellow reserve driver Sakon Yamamoto was in regular Bruno Senna’s car at Istanbul, the Austrian had said 24 hours ago that he expects to appear again in free practice sessions in 2010.

Klien, 27, drove in Karun Chandhok’s F110 in Barcelona, but he will be unable to travel to the forthcoming Canadian grand prix due to the clashing Le Mans 24 hours.

“I had a very good debut in Barcelona, where I was immediately faster than Bruno Senna, who has been sitting in the car all season,” Klien is quoted by German Sky television.

“It is expected that I will sit again in the car in Valencia, and then we will see.  As they say, step by step.”

Nick Heidfeld has admitted he is prepared to become F1′s tyre tester later this year.

With Bridgestone departing and a new supplier set to enter formula one in 2011, it has been rumoured that amid the current testing ban, some tyre-specific track outings might be sanctioned.

“That would be an attractive thing. If I am asked, I would not say no,” German Heidfeld, who this year is Mercedes’ reserve driver, is quoted by Sport Bild magazine.

The 33-year-old is a veteran of 167 grands prix, and he is bidding to be back on the F1 grid in 2011.

“I want to be racing again (in F1) no later than 2011,” he confirmed.

“I feel too young for DTM or for taking part in the Le Mans 24 hours,” added Heidfeld.
