Red Bull’s Formula 1 driver pairing of Max Verstappen and Sergio Perez have not appeared best pleased at the reigning constructors’ champions so far this weekend in Mexico City.

The pair endured tricky practice sessions across Friday and Saturday’s proceedings, the RB20 frequently prompting severe complaints from the stars over team radio.

By close of the session however, Red Bull had been left rather humiliated, the Dutchman only managing to set the fourth fastest time after he was forced to return to the garage when his Red Bull experienced major power issues.

Perez on the other hand finished way down in 10th, with potential replacement Yuki Tsunoda ahead of both Red Bull drivers in third.

Friday’s second practice session made matters even worse for the team as Verstappen was forced into an early retirement from the session, his engine troubles having persisted.

Hoping to start Saturday’s runs with a clean slate, the pair headed into FP3 with high hopes, particularly three-time champion Verstappen, after the team changed the power unit on his machinery ahead of the final practice session and qualifying for Sunday’s race.
