But the highly respected Brazilian correspondent Livio Oricchio claims 41-year-old Barrichello - the most experienced driver in F1 history - could even race the Sauber at his home race at Interlagos for November's 2013 finale. Oricchio said Barrichello is currently not answering his phone.
"He just sent a message saying 'who knows'," he wrote in O Estado de S.Paulo newspaper. And Oricchio said F1 chief executive Ecclestone answered "good" when told of the prospect of Barrichello's return. (GMM)
