Mercedes will wait until the New Year before making any announcement on a replacement for retired world champion Nico Rosberg, with Finland’s Valtteri Bottas still the favourite.
A team spokesman said nothing was planned between now and January 3 and there was no significance in the latter date either, other than it marking the end of the holidays.
Bottas has become the bookmakers’ favourite but neither his Williams team nor Mercedes have confirmed any approach has been made.
Rosberg surprised both his team and the sport by announcing his retirement five days after winning the championship in Abu Dhabi at the end of November, leaving Mercedes in a difficult position.
The sport’s dominant team, who have won both titles for the past three years in a row, have the most desirable seat on the grid up for grabs but a shortage of experienced contenders who are also available.
The likes of double world champion Fernando Alonso, at McLaren, and Ferrari’s four times title-holder Sebastian Vettel have ruled themselves out.
“We have an agreement with McLaren and we are going to respect that,” Alonso’s manager Flavio Briatore told Italy’s Gazzetta dello Sport last week.
Bottas, 27, is under contract to Mercedes-powered Williams but has had management ties to Mercedes team boss Toto Wolff since he entered the sport.
