Mick Schumacher was disappointed with Haas' strategy calls after being unable to translate a Q3 appearance into a points finish.
Starting the Spanish Grand Prix from 10th place, the Haas driver launched himself up to sixth place at the start of the race.
However, Schumacher fell down the order over the course of the race and finished in 14th place.
Speaking after the race, the 23-year-old pointed the finger at the Haas' two-stop strategy, which went against the three-stopping trend from most other drivers.
"We probably took the wrong decision on staying on 'Plan A' and not diverting to something else," Schumacher told media, including RacingNews365.com.
"It's quite gutting, but we will analyse it as a team and we will hopefully come back stronger as a team.
"The tyres were pretty finished in that last lap [before first pit stop] but then also I think we had a not a great pit stop from what I understand.
"It's just something we have to understand; where it went wrong, where we could have improved and where we should have done the switch to the other strategy."

Schumacher buoyed by pace despite pointless race
The Haas team were able to put together a strong performance at the Spanish Grand Prix, despite going against the grain and not bringing any updates to the Circuit de Barcelona-Catalunya.
With Schumacher starting in 10th and teammate Kevin Magnussen lining up in eighth, the team were looking to score points for the fourth time in six races.
Magnussen's lap one tangle with Mercedes' Lewis Hamilton helped promote Schumacher to sixth place on the opening lap, before the German started falling away.
Schumacher added that whilst he was very happy with his start, it wasn't much of a distraction from the disappointment of lost points.
"It's unfortunate because we had a good start and we were in a good position, but then the other tyres just didn't last as we expected them to," added Schumacher.
"It was very fun to be up there with everybody and we had such a good start. Then, frustrating that we didn't have the pace to stay there."
