Valtteri Bottas says he has a "Plan B" and "even a Plan C" in case he is not retained by Mercedes as Lewis Hamilton's teammate next year.
The Finnish driver is second in this year's drivers' championship but faces an uncertain summer break as he waits on Mercedes to decide on his contract option for 2020. He faces competition for the drive from reserve driver Esteban Ocon, with Mercedes team boss Toto Wolff planning to make a decision during F1's summer break.
Bottas started the year with two wins from the first four races, but his form has dropped off at recent rounds and he now trails Hamilton by 62 points in the drivers' standings.
