All eyes are on Mercedes' Kimi Antonelli, who can make history this weekend. The 20-year-old needs just two points to secure the title on Sunday and become the youngest-ever F1 world champion. The Italian could also be crowned without scoring any points if neither Russell nor Hamilton wins the race.

Mercedes could also secure the constructors' title at the Autodromo Hermanos Rodriguez, with the Silver Arrows needing to outscore Ferrari by at least 39 points. The Scuderia, however, have looked strong in the earlier practice sessions.

Meanwhile, the stewards have already been busy during the Mexico City GP weekend, with both Max Verstappen and Liam Lawson set for a one-place grid penalty for Sunday's race. The stewards' verdict follows an incident in FP2, when Verstappen and Lawson collided in the slow stadium section of the track. The two drivers also have an extra penalty point for what they both later agreed was an "unnecessary and clumsy" incident.

The stewards have also had to approve a late change to the Grand Prix entry list after Haas made the shock announcement that Esteban Ocon will not participate in the remainder of the Mexico City weekend.

Replacing Ocon is 32-year-old Ryo Hirakawa, a two-time winner of the FIA World Endurance Championship and 24 Hours of Le Mans Winner with Toyota GAZOO Racing. The Japanese driver already participated in FP1 at the Autodromo Hermanos Rodriguez this weekend.

At 32, Hirakawa will become the second oldest Grand Prix debutant of the 21st century - behind only Andre Lotter for Caterham at the 2014 Belgian GP.

In their statement, Haas gave no comment as to why Ocon - set to be replaced by Rafa Camara in 2027 - has withdrawn from the Grand Prix weekend, but GPblog understand that disciplinary action has seen the Frenchman leave the F1 team entirely.
