The Australian driver, 34, qualified an impressive fourth for Red Bull’s junior team AlphaTauri and finished seventh, their best result of the year.

Asked if he would stand by Perez, Horner’s answer came with provisos. ‘Yes, he has got three races to cover off that second place,’ he said.

‘There are 20 points between him and Lewis [Hamilton, a strong runner-up for Mercedes in Mexico].

‘He has had some misfortunate and some issues, but we still believe he can do it between now and the end of the year.’

Pressed on whether finishing second was a condition of remaining at the world championship-winning team, Horner said: ‘It is not as binary as that. You have to look at the circumstances and so on, and Checo [Perez] has an agreement with us for next year and it is our intention for him to be in the car in 2024.

‘We will give him all the support he needs to ensure he finishes second, but there is no prerequisite that if he doesn’t finish second he is out of the team.’

In contrast, Horner waxed lyrical about Ricciardo, who was handed the AlphaTauri seat before the summer break.

He won seven of his eight grands prix at Red Bull before moving to Renault in 2019, prior to a curiously difficult two seasons at McLaren.

Horner said: ‘It was great to see Daniel perform so well and it endorses our decision to bring him back [at AlphaTauri].

‘I thought he was outstanding this weekend, fighting a Mercedes in an AlphaTauri, and, if it weren’t for the red flag, he would have finished further up.

‘It was a remarkable performance from him. He is back to his old self. He is relaxed and confident.’

There is an easy solution open to Horner, namely placing Perez at AlphaTauri in Ricciardo’s place. That looks the most likely outcome right now.
