Alguersuari waits; Manor to drive as Virgin Racing

Paris: Motor racing's governing body released the Formula One lineups for next year on Monday, revealing that Spanish driver Jaime Alguersuari's position at Toro Rosso could be uncertain and new team Manor GP will drive as Virgin Racing.

FIA said Sebastien Buemi was the only driver listed for Toro Rosso's two positions. Alguersuari had replaced Sebastien Bourdais of France late last season.

"Jaime's contract has been signed and renewed for next season so this is very surprising news," the driver's management team said in a statement. "Jaime is, as we speak, undergoing physical and psychological training with the Red Bull team in Austria in preparation for the upcoming season."

2010 car will be more aggressive: McLaren

The British-based Manor team has signed German driver Timo Glock. Virgin, which was on Brawn GP's championship winning cars last season, is yet to confirm it is sponsoring Manor.

Only 12 teams were listed, although FIA said a 13th would be named "in due course."

"Toyota Motorsport remains formally bound by the Concorde Agreement to put forward a team for participation, though it has indicated that it will not be in a position to do so," the FIA said in the statement.

Sauber is the most likely candidate to replace Toyota, which followed Honda and BMW and pulled out of the sport due to rising costs.

Peter Sauber, who acquired his former team back from BMW after it pulled out of the sport, is confident he will receive the 13th slot.

"Regarding the slot on the grid, I am very confident that we will be given a final confirmation very shortly," said Sauber, who added that the team's 2010 car was on schedule and would use Ferrari engines.

World champion Jenson Button was confirmed as the No. 1 driver ahead of new McLaren teammate and 2008 champion Lewis Hamilton.

Button's former team, Brawn GP which will now be called Mercedes GP, has the next two places with Nico Rosberg in at No. 3.

Also, Red Bull will stick with Renault engines.
