The German driver Nico Rosberg has warned his Mercedes teammate Lewis Hamilton ahead of Spanish Grand Prix on Friday.
Rosberg, who has beaten Hamilton in the practice race ahead of the main event, said that his best was yet to come, the Mirror reported.
The German driver, who is 33 points behind Hamilton, is currently at the second spot in the driver's standing.
Critics have been writing off Rosberg who has fallen 27 points behind his teammate just after four rounds.
However, Rosberg feels that he is confident about repeating his last summer's performance in which he won two out of three races.
