SAO PAULO, BRAZIL - RENAULT will announce their 2009 Formula One driver line-up on Wednesday, team boss Flavio Briatore said on Sunday.

'Wednesday is the day. We will announce both drivers on Wednesday,' he told Reuters at the Brazilian Grand Prix.

Spain's double world champion Fernando Alonso, who finished second at Interlagos after winning in Singapore and Japan, is expected to stay at the team although Honda have made him a target.

However, his team mate remains uncertain, with Brazilian rookie Nelson Piquet fighting to keep his place after a difficult season.

France's Romain Grosjean and Brazilian test driver Lucas di Grassi have both been named as possible replacements at the former champions.
