Red Bull team principal Christian Horner has admitted that there is pressure on Sergio Perez after what has been a difficult season for the Mexican driver.
There had been some reports of an ultimatum between Red Bull and Perez, that he must finish second in the drivers' championship, or have his contract ripped up a season early.
With Lewis Hamilton's disqualification from the United States Grand Prix, Perez finds himself 39 points ahead of the Brit in third, with four races left.
“Hopefully, he can build a good performance," Horner told Sky Sport Italia.
"He did a great race last week with a great pace, so if he keeps the same confidence, he can do great.
“Listen, there is always pressure in Formula 1 contract or no contract. We know what Checo is capable of. There was never a discussion about him leaving the team.”
