Teenager Kimi Antonelli crashes in F1 practice debut for Mercedes at Italian GP

Teenager Kimi Antonelli's Formula 1 debut lasted 10 minutes on Friday. Antonelli, who only turned 18 on Sunday, was involved in a high-speed crash in practice for the Italian Grand Prix.

He lost control of his Mercedes car at the iconic Parabolica corner, spinning off the track and flying through the gravel trap into the barriers, knocking off the front wing of the car.

A distraught-sounding Antonelli was swift to apologise on the radio and was immediately reassured by Mercedes team principal Toto Wolff.

Antonelli is widely expected to be announced as George Russell's teammate for next season, replacing the Ferrari-bound Lewis Hamilton.

The Italian driver was given his first taste of what it would be like to step up when he was given Russell's car for the opening practice session at Monza.

The session had to be stopped for nearly a quarter of an hour after the crash. Antonelli was checked over at the medical centre before walking back to the Mercedes garage, where he was given a big hug by Wolff.
