Piquet under pressure

The word in the paddock in Monaco is that Renault's second driver Nelson Piquet Jr is under pressure from the team to improve his performance or may find himself replaced within the next few races. The rumors suggest that the drive could go to either Takuma Sato or Anthony Davidson, the two men left without work after the demise of Super Aguri, or by Force India F1 test driver Tonio Liuzzi.
