Romain Grosjean believes there will only be movement in the driver market once Fernando Alonso and Ferrari have made their moves.
Two-time World Champion Alonso has been strongly linked with a switch back to McLaren, but both the Spaniard and Ferrari have this week insisted that he will remain at the Maranello for the 2015 season.
However, the speculation has refused to die down and Grosjean, who has indicated that he will be willing to leave Lotus in search of glory, says things will only pick up once Alonso's future is confirmed.
"It's been quite quiet to be fair, nothing crazy," he is quoted as saying on espn.co.uk. "You have to wait for Ferrari and Alonso and by then the market will have moved. I'm sure you are aware as much as I am, if not more, and so far nothing has moved much.
"You can always do speculation and from what I know all the other drivers have a contract in the big teams. Alonso is the key of the market."
Asked if he'd been in talks with Ferrari he said: "There are always talks and that's why there are managers. There have been a few talks, but you'll just have to wait."
