Thursday 4 February at 08:31 : Feb.4 (GMM) The ambitious Stefan GP outfit may have this week hammered the final nail into the coffin of the 2010 formula one entrant Campos.

Germany's Auto Motor und Sport, and Finland's Turun Sanomat, report that notwithstanding A1 boss Tony Teixeira's desire to buy into Campos, the Spanish team may be unable to race this season.

Because Campos fell behind in payments to its car constructor Dallara, the Italian company may have sold the rights to Campos' car to Stefan GP.

It means that even if Campos comes up with the money to pay its overdue bills, including to the engine supplier Cosworth, it will not have a car for 2010.

Stefan GP reportedly does not intend to actually use the Campos/Dallara chassis, because it is well advanced with preparations to run Toyota's 2010 package.

In addition to Kazuki Nakajima and Ralf Schumacher, also Jacques Villeneuve is being linked with Stefan's 2010 plans.

It means Bruno Senna's grand prix debut is now uncertain, and the Brazilian admitted on Wednesday that Campos will "hopefully" begin winter testing "in the near future".
