Who will replace Nelson Piquet at Renault?
After a season and a half, Nelson Piquet's tenure as an F1 driver is at an end, with a strongly worded statement from the Brazilian confirming what many expected - that he is to leave the Renault team.
It leaves the French squad looking for a team-mate for Fernando Alonso, although the team also has the small matter of an appeal to deal with before it discovers if it can compete in the European Grand Prix in Valencia.
In terms of who could replace Piquet, a number of names are likely to crop up - including GP2 front-runners Romain Grosjean and Lucas di Grassi. Former GP2 race winner Bruno Senna will be another driver linked to the seat, while ousted Toro Rosso driver Sebastien Bourdais would be a high-profile French option.
Another French option could be found in the shape of F3 Euroseries leader Jules Bianchi, while Renault Development Drivers Davide Valsecchi and Charles Pic would also hope to be given their chance. Should Renault look down to the current World Series grid, they could do worse that points leader Bertrand Baguette.
Of course, any one of a number of other drivers will thrown their name into the hat, but who do you believe is likely to be signed up as Alonso's partner?
