Lewis Hamilton admits he could follow former team-mate Nico Rosberg out of Formula 1 as early as the “end of this year.”

The 32-year-old is currently embroiled in a battle with Sebastian Vettel for the 2017 Drivers’ Championship title.

Should Hamilton come out on top, it would be the Briton’s fourth World title, putting him third on the list along with Vettel and Alain Prost.

However, four is where it may yet stop.

“My destiny is in my own hands. I can decide to stop at the end of this year,” the Mercedes driver told the FIA’s official in-house magazine Auto.
