Nico Rosberg has admitted to frustration with his situation this year at the Williams team.
The impressive German youngster is regularly the quickest competitor outside of the top three teams in 2007, and is increasingly linked with upcoming moves to further his career.
In the German magazine Sport Bild, it is suggested that 22-year-old Rosberg, who debuted for Grove based Williams last year, is frustrated with reliability, a weak Toyota engine, and the fact that any public criticism earns him a rebuke from his team bosses.
Asked about his current situation, he admitted: “Lately, things do not go so well.
“It is more and more difficult to score any points. The top three teams normally reserve the first six positions, and the world champion Renault becomes ever stronger.”
Rosberg would not comment upon whether he thought the team had, at the expense of reliability, risked too much to move closer to the top teams.
“Officially, I can only say no,” he said.
“I cannot say too much, except that reliability is a problem. It doesn’t help anyone to criticise in the public.”
He admitted, however, that his team bosses Sir Frank Williams and Patrick Head do respect his on-track achievements so far this year, including regularly outpacing experienced teammate Alex Wurz.
“Frank and Patrick are not the kind of people who praise you deeply when you take the car to the maximum. But I do feel that the respect of the team for me continues to rise,” said Rosberg.
