Lewis Hamilton has sent a Max Verstappen message to McLaren duo Lando Norris and Oscar Piastri.
Following the summer break, Verstappen has cut the gap in the Championship race up to 40 points with Piastri.
The drivers are currently preparing for the race in Mexico.
"Obviously, they've won championships in other categories," said Hamilton to Sky Sports F1. "In that scenario, it's challenging when you are in the team, the pressure is high.
"It's definitely a time where you really have to put your blinkers up. You have to block absolutely everything from the outside, because there's so much coming in - positive and negative. Also, you really have to be cutthroat. That's what Max is. He's going to take this from them if they don't do the same.
"They've got to be pushing, and you've got to dig deep to be able to hold off someone like Max and the car that he is in at the moment, but also for either of them to come out ahead. Consistency is key, and you've seen that from Max in the last few races."
