Kimi Raikkonen's interest in driving for Renault next year is "flattering", team boss Eric Boullier has admitted.
2007 world champion Raikkonen's manager last week confirmed reports the pair had spoken with Boullier about the vacant 2011 seat alongside Robert Kubica.
The 30-year-old Finn switched to world rallying this year after winning 18 Grands Prix with Ferrari and McLaren last decade.
"It's flattering," Boullier said in a French language report of the Agence France-Presse agency, "because it shows that our team is again attractive to a Formula One world champion."
After Fernando Alonso's titles in 2005 and 2006, Renault entered a period of decline that resulted in the French carmaker selling to Luxembourg based Genii Capital at the end of last year.
"Our simulations show that our car has improved by about 1 and 3/4 seconds between the first test and now. We have been one of the teams with the greatest progressions.
"That is a true source of satisfaction," admitted Boullier. "We have proved the team has the qualities to operate at the highest level."
