Red Bull boss Christian Horner has piled more pressure on Sergio Perez as the Mexican sweats over his Formula 1 future.
The 34-year-old has endured a miserable campaign so far, and currently finds himself eighth in the drivers' standings, almost 200 points behind team-mate Max Verstappen.
His 10th-place result at last weekend's Singapore Grand Prixextended his run of races without a podium finish to 13.
Despite being rewarded with a new deal earlier this year, Perez has failed to improve his performances, scoring just 59 points since coming home third at April's China GP.

The British outfit - spearheaded by Lando Norris and Oscar Piastri - currently hold a 41-point advantage over the defending champions, and with six races to go, appear firm favourites to clinch a first title since 1998.
“I think that we need to have two drivers firing on all cylinders," said Horner.
“Checo had a good weekend last weekend [in Azerbaijan]. He had a tough weekend this weekend.
"We need to put some weekends together where you can see where McLaren are putting two drivers on the podium - it’s those big points that really make a difference.
“So, you know, we need to make sure that Checo goes as far off the field as we can get it, in terms of finding the right direction.”
