Tough ultimatum: Formula 1 star threatens disaster season. Ricciardo still has two races left.
Boss Helmut Marko is said to have made it clear that Ricciardo should perform well in Japan and China in April. If the Australian underperforms there too, there should be a driver change. The Racing Bulls in particular, as a sub-team of Red Bull, have been known for numerous driver changes in recent years. The paddock will pick up speed next season at the latest with Lewis Hamilton's move to Ferrari.
