Championship leader Kimi Antonelli maintained his strong form by setting the fastest time for Mercedes in Saturday's crash-interrupted final practice session ahead of the Belgian Grand Prix.

The Italian teenager, who also topped Friday's running, produced a blistering lap of 1 minute, 45.990 seconds to finish 0.139 seconds ahead of McLaren's defending world champion, Lando Norris. Four-time world champion Max Verstappen was third for Red Bull.

Norris is set to serve a 10-place grid penalty for Sunday's race.

George Russell recovered to finish fourth, three-tenths of a second behind his Mercedes teammate after struggling to match Antonelli's pace throughout the session. Lewis Hamilton was fifth for Ferrari despite crashing heavily in the closing moments of practice.

The seven-time world champion lost control at the Fagnes chicane and ran wide, sending the right rear of his car into the barriers, much like Pierre Gasly did for Alpine on Friday.
