Ralf Schumacher believes that Haas need to contain their drivers Mick Schumacher and Nikita Mazepin after recent incidents seemed to cause division.
Mick was left furious when an aggressive move from his teammate in the latter stages of the French Grand Prix forced him to take evading action. There were also issues at the previous event in Azerbaijan when the pair almost collided on the sprint to the chequered flag as Mazepin moved to block Mick in the last moments.
Whilst Mick's uncle Ralf can acknowledge that such public disagreements can be entertaining for fans, he also believes that Haas need to get the situation under control before there is further damage.
"For us spectators, it's a part of the entertainment," former F1 driver Ralf told Sky Sports. "The fact that the drivers express criticism publicly - even if it's uncomfortable and intra-team - makes us happy.
"But it is now up to the team to contain both drivers. The only bad thing for Haas is when senseless accidents result from such situations and money is used up that is actually urgently needed for development.
"Budget capping is an issue and that would be the lever for team boss Guenther Steiner to bring calm into it now and introduce internal team rules. We did it that way in the past. In certain corners and certain positions, it was very clear who owned the corner. Then it's much easier."
Ralf thinks that Mick has proved himself to be the stronger driver, but understands that rookies in Formula 1 need time to find their feet.
"Looking back on the whole year, Mick is in his own league - unlike his teammate," Ralf said. "The six-tenths lead in qualifying showed that again. But also the race itself, when Mick had problems at the beginning, was already 15 seconds behind Mazepin and still finished ahead of him.
"That shows his potential. But again: It's up to the team manager to bring calm and rules into the race and then everything will be fine. The rest is just youth. I think it's good that they can learn that way. Everyone knows that when two rookies start out, it's not always easy."
