Jul.29 (Inautonews.com/GMM) Nick Heidfeld in Hungary insists he is neither worried about his Renault seat nor the criticisms attributed this week to his boss Eric Boullier.

“I do not fear for my cockpit,” said the German, who on Friday morning is giving up morning practice for team reserve Bruno Senna.

“It has been considered for some time to let Bruno do a practice session. Of course I’d rather be in the car because every session helps you to prepare,” Heidfeld told Auto Motor und Sport.

But according to Der Spiegel, the 34-year-old scheduled a meeting with Boullier when he heard about hefty criticisms uttered since the Nurburgring.

Heidfeld insisted: “I’ve been in formula one long enough to know that something is not eaten as hot as it is made. You never know what really was said or what was intended.

“It sounds critical, but first I want to talk to him myself. I’ve arranged to meet with him on Friday.”

The current speculation is that Heidfeld is definitely not staying at Renault beyond 2011, and the veteran admitted at the Hungaroring that he always keeps his “eyes open” for new opportunities.

One of them might be the German touring car series DTM, where his former employer BMW will be racing next year.

“With three manufacturers, (racing in) DTM is clearly imaginable to me,” Heidfeld is quoted by sport1.
