Nick Heidfeld will be in no doubt as to the need to emerge quickly from his performance crisis, former BMW-powered driver Ralf Schumacher said on Monday.
Heidfeld, the 31-year-old who finished dead last at Monaco on Sunday, deepened his run of poor form after struggling in 2008 to match the impressive performances of his young
BMW-Sauber teammate,
Robert Kubica.
BMW boss Mario Theissen has already alluded to the need for all team members to "contribute" to the outfit's progress.
Schumacher, who was BMW-powered at Williams between 2000 and 2004, told the German newspaper Bild when asked about Heidfeld's form: "Clear words are spoken at BMW; expectations are very high."
Heidfeld on Sunday afternoon was not keen to embrace the concept that Monaco proved he is spiralling into a crisis.
But he acknowledged: "It is obvious that I am not getting all the speed out of the car."
