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 Mc Laren's Lando Norris by 106 points. Just nine rounds remain this year, starting with this week's Azerbaijan Grand Prix which will see the race take place on Saturday at 12pm, live on Sky Sports F1 and Sky Sports Main Event.

Speaking on the latest episode of Sky Sports' The F1 Show, Rosberg brought up his own title-winning experience in 2016 where he faced a big mental battle which Antonelli may also need to overcome. "I know how my head started to play games with me when I was the big favourite," said Rosberg. "When you're really the big favourite, like he is now, it's like, 'oh my God, this is this is actually mine for the taking. I better not mess this up...'

Antonelli has shown no signs of any nerves as he has won the last two races, including an incredible drive from 19th to first at his home event at Monza, then at a new track in Madrid a week later. In 2016, Rosberg was in a much tighter title fight against Hamilton but was in a position where he did not need to win the last four races.
