Force India driver Esteban Ocon described the Mexican Grand Prix as "probably the worst race of his F1 career".
Ocon, who looks set to miss out on an F1 seat for 2019; damaged his car in the opening lap of the race - and consequently finished outside of the points.
"This has been probably the worst race of my whole Formula One career so far," Ocon told RaceFans. "Nothing went our way and it's just been a terrible afternoon."
The French driver started 11th on the grid, which allowed him to start on more durable tyres than the four cars ahead of him.
"I made a very good start, managed to pass the two Saubers on the run down to turn one, but that is pretty much the only positive to take from today," Ocon continued. "I went alongside Carlos (Sainz Jr) in turn three, but I saw he was going to turn in.
"I braked to avoid a collision, but we still made contact and it broke my front wing. I had to pit at the end of the first lap and my race was effectively over.
"It's a shame because we had a good strategy and a fast car, but today was not our day. Let's just forget about this race and come back stronger in Brazil."
Force India finished pointless, with Ocon's team-mate Sergio Perez retiring from his home race in Mexico.
