One thing to say, Callum, is Alex Albon was very diplomatic in his response to Fernando Alonso's comments, saying the Spaniard was a driver he has always looked up to. The two also shared a jokey moment on the fan stage earlier on.

Oscar Piastri has a short stay at the top of the timesheets on the hard tyre but Lewis Hamilton has nicked his place with a marker of 1:18.741 on the medium compound.

World champion Lando Norris is running the opposite tyres to Piastri, so he's also on hte yellow medium compound and has just gone third.

Ferrari's Charles Leclerc led Mercedes driver Kimi Antonelli in first practice at the Mexico City Grand Prix, where the Italian is poised to clinch his first world title.

Leclerc was 0.659 seconds quicker than Antonelli, for whom a ninth-place finish will secure the championship regardless of any other results.

Only a victory by his team-mate George Russell or Ferrari's Lewis Hamilton can theoretically stop Antonelli becoming champion on Sunday. Even then, Antonelli only needs ninth place if Russell wins and 10th if Hamilton does.

Third quickest in the session was Mercedes reserve Frederik Vesti, driving Russell's car, ahead of Hamilton.

Mercedes were one of 10 teams to choose this session to do one of their mandatory rookie sessions. Only Ferrari had both race drivers in their cars.

With a gap of 123 points to nearest challenger George Russell, Kimi Antonelli has one hand on the trophy as we head into the Mexico City weekend.

Either Mercedes' team-mate Russell and Ferrari's Lewis Hamilton, who is 124 points behind Antonelli, have to win the race at the Autodromo Hermanos Rodriguez and hope the Italian finishes outside the points, so the title is really the 20-year-old's to lose on Sunday.

The fight for second place in the drivers' championship, though, is still very much on. Russell has it, but Hamilton, fourth-placed Max Verstappen and Charles Leclerc in fifth are right on his tail, with nine points separating the chasing pack.
