Rosberg: Antonelli vs his mind will decide F1 title race

Former Formula 1 world champion Nico Rosberg believes Kimi Antonelli's biggest obstacle will be himself in this season's title race run-in.

Antonelli is on course to become F1's youngest world champion at 20 years old as he leads Mercedes team-mate George Russell by 81 points, Ferrari's Lewis Hamiton by 101 points and McLaren's Lando Norris by 106 points.
