2010 rookie Nico Hulkenberg's race seat at Williams is in doubt for next season, according to Italian reports.
Autosprint magazine says the British independent team is set to lose four sponsors at once, including RBS and Philips, and it's rumoured that German Hulkenberg's famous manager Willi Weber is asking Sir Frank Williams for a pay rise for his 23-year-old charge.
The first name mentioned as a potential new team mate for Rubens Barrichello is Pastor Maldonado, who is about to succeed Hulkenberg as GP2 champion.
Venezuelan Maldonado, 25, is backed by state oil company PDVSA and had hoped to go to Sauber but that team has instead signed the Telmex-sponsored Sergio Perez.
Williams' third co-owner, Toto Wolff, said last weekend he was not expecting "a lightning-fast decision" about the team's 2011 drivers.
"I feel quite comfortable about our driver line-up," he told Kleine Zeitung newspaper.
