Red Bull team boss Christian Horner has hinted Daniel Ricciardo’s test this week is a 2014 audition as the world champions look to replace the departing Mark Webber.
The news is a blow for Australian Ricciardo’s similarly 23-year-old Toro Rosso teammate Jean-Eric Vergne, who earlier was also considered in the running for the top seat alongside Sebastian Vettel.
Unlike Ricciardo, Frenchman Vergne has not been called up to test the championship-leading RB9 at the Silverstone test.
“We’re very keen to have a look at Daniel as a prospect for next year”, Horner told British broadcaster Sky.
“It’s a great opportunity for him,” he added.
Horner also said that 2007 Champion Kimi Raikkonen is in the running for the seat.
Asked if it was a two horse-race between the Finn, who drives for Lotus, and Ricciardo, Horner replied, “probably”.
