Kevin Magnussen believes Haas "cannot cry" at its current lack of performance in Formula 1 as he identified a "paradox" within the team.
The Italian Grand Prix was Haas's worst two-car finish of the season as it finished last and last but one with Nico Hulkenberg 17th and Magnussen 18th at Monza.
It was a difficult weekend for the team with the VF-23 struggling at the high-speed circuit as Haas's point-less run in a Grand Prix extended to 10 races since Magnussen was 10th in Miami.
High tyre degradation has plagued the car all season, but new parts are on the way for the team, who sits eighth in the Constructors' standings.
Dane Magnussen, now in his sixth season with Haas, believes the car to be the worst he's had, but is optimistic of a reversal in fortunes soon.
Viewed by others:
"The work is being done in the background, and we just have to be patient on that until we can bring the parts to the car," Magnussen told media including RacingNews365.
"At the end of the day, we've got a job to do and we need to crack on until we get those parts and we can't cry about what we've got at the moment.
"We've got to work with what we have, and try to get something out of it no matter how difficult it looks.
"I still believe that the team is in a stronger place than it has ever been, it is just a paradox that we've probably got one of the weakest cars we've had with the strong foundations that I see in the team.
"We can do a lot better and I think we will do so, it really is a patience game.
"It is about sticking it out with what we have at the moment, and waiting for better things."
