Haas drivers Kevin Magnussen and Mick Schumacher were left frustrated after the French Grand Prix, as both drivers saw their two-race points scoring streaks come to an end.
Magnussen retired with damage sustained in a clash with Nicholas Latifi on Lap 39, while Schumacher finished 15th and last after being pitched into a spin while overtaking Zhou Guanyu.
Having started last following a grid penalty for excessive component usage, Magnussen was making his way through the field when the Latifi incident halted his charge.
"He attacked and ran me out of road," Magnussen told media including RacingNews365.com of his clash with Latifi, who also retired after sustaining damage.
"And then, on the right side, we made contact, but there was nowhere I could really go except off the track.
"I think he should have given me more space, but you have to go and see it again on television and then judge from that."

Schumacher bemoans events of French GP
Schumacher's tangle with Zhou came later in the race, as the German was attempting to overtake the Alfa Romeo around the outside of the fast Le Beausset right-hander.
Just as it looked as if Schumacher had managed to get the job done, a snap of oversteer forced Zhou into a correction to the left, clipping Schumacher's right-rear tyre and sending the German into a spin.
Speaking afterwards, the German lamented a series of unfortunate events that contrived to ruin his afternoon.
"We had a difficult start on the Medium [compound tyre]," Schumacher told media including RacingNews365.com.
"The tyre just didn't really work as well as we imagined. We knew it was going to be tough, but not this tough, so we came in [to pit] early.
"Unfortunately, there was a Safety Car, which meant for a lot of people that it was a free stop, so we were quite far back.
"And then we had the contact with Zhou, so overall quite tough.
"Nonetheless, we learned some stuff and hopefully we have a better weekend in Budapest."
