Bernie Ecclestone has said Formula One is making “a big push” to have Grand Prix in the Russian city of Sochi, host of the 2014 Winter Olympics.

Contracts to host Grand Prixs in some European cities are soon to run out and will not be renewed, Reuters reports.

"We've got two or three places in Russia which we're dealing with at the moment," Ecclestone told reporters before touring the circuit being built in South Korea that will host its first Formula One race this October."There is a big push for us to do something with Sochi."

Ecclestone added that he was “absolutely sure” that the Korean circuit would be built on time for this year's race, following a report in a German magazine which claimed the designer of the circuit, Hermann Tilke, had expressed concerns it would not be ready."I've spoken to Tilke and he denies saying it." Ecclestone said.
