Sauber team boss Monisha Kaltenborn criticised both Marcus Ericsson and Felipe Nasr for their Monaco Grand Prix crash that ultimately caused the retirement of both drivers.
The financially-strapped team had requested Nasr to allow the faster Ericsson through to attack the drivers they were following in the race, only for the Brazilian to reject the request, with Ericsson then taking matters into his own hands and attempting an overtake at Rascasse that saw the two collide.
Within a handful of laps, both had pulled into the pits to retire, and Kaltenborn read the riot act to both Nasr and Ericsson, and insisted that this kind of incident will not happen again.
“It was unacceptable behaviour by both drivers,” said Kaltenborn. “Today the work of the whole team ended in a collision.
“Marcus and Felipe both know how much work is put into every race weekend. They have the responsibility to make it to the end of the race.
“After evaluating the overall situation, it was important to bring the fastest car as far as possible to the front, so that we were able to use any chances. Our decision was based on the data from both cars.
“After this, we have clarified the situation internally and both drivers are aware of their responsibilities. Such an incident will not happen again.”
