'Close to perfection,' 'A very big heart' - what F1 rivals think of boy-king Kimi Antonelli

20-year-old Kimi Antonelli is on the verge of becoming the youngest Formula 1 World Champion in history, needing to finish ninth or higher at the Mexico City Grand Prix on Sunday to clinch the title. He replaced seven-time champion Lewis Hamilton at his team after Hamilton moved to Ferrari, and has impressed rivals throughout the season with performances described as 'close to perfection.' Antonelli recently won the United States Grand Prix comfortably and can also secure the championship if Hamilton or George Russell fail to win in Mexico.
