Haas team boss Guenther Steiner has set Mick Schumacher the task of "still getting better" as his second F1 campaign develops.
If follows a surge in form from the German, son of seven-time World Champion Michael, with back-to-back points finishes achieved in Britain and Austria.
Schumacher had been criticised by Steiner earlier in the season for a sequence of costly crashes, while struggling to match the pace of teammate Kevin Magnussen.
But he turned his form around to claim a maiden points finish at Silverstone (placing eighth) before backing it up with a top-six result at the Red Bull Ring.
Steiner impressed by Schumacher, but wants even more
Schumacher's weekend in Austria also included confidence-inspiring battles with Lewis Hamilton, who ties father Michael on seven F1 titles.
Reflecting on this recent progress, Steiner recognised the steps being made but called on the 23-year-old to continue his upward trajectory.
"Everybody has to prove himself and he's doing good at the moment," Steiner told media, including RacingNews365.com.
"Hopefully he will still [get] better, because we need it for the team [and] we need to make points."

As for how this might affect Schumacher's future, and his chances of remaining at Haas for a third season, Steiner remained tight-lipped.
"What does it do for his future? I don't really know yet; it's early to talk about the future," he continued.
"We haven't decided on the drivers and we never did before the summer break, as you well know.
"We will decide after the summer break and see, but I don't know what else he's up to."
Schumacher sits 15th in the Drivers' standings, four places and 10 points adrift of Magnussen, while Haas hold seventh in the Constructors' battle.
