Ricciardo suffered his eighth retirement of the year and dropped out when he was on course to claim his first podium finish since Monaco earlier this year. Ricciardo, who will leave Red Bull for Renault at the end of the year, stated that the car is cursed and Pierre Gasly can drive the remaining two rounds.
"He just had an immensely frustrating afternoon," the Red Bull team principal stated after the race. "You can understand his frustration and hope that this dark cloud that's following around lifts for the final two races."
Ricciardo was fending off former teammate Sebastian Vettel in the latter stages of the race. Horner believes that the issues Ricciardo had were similar to those Max Verstappen had during practice in Mexico.
"It's gutting not just for him but the whole team, because we were looking at potentially a one-two finish which has enormous value to us," added Horner. "So it feels a bittersweet victory. Fantastic for Max to have driven an outstanding race, an absolutely outstanding race, but I'm pretty confident Daniel that would have been able to hold off Sebastian [Vettel] over those remaining laps."
