Sauber team boss Monisha Kaltenbron has vented her anger at duo Marcus Ericsson and Felipe Nasr for taking each other out at the Monaco Grand Prix.
The team ordered the Brazilian to make way for the Swede as they felt his teammate was more competitive on Sunday, but Nasr refused to obey they order which prompted a frustrated Ericsson to take matters into his own hands and attempt an overtake.
The two ended up colliding at Rascasse, something which Kaltenborn deemed unacceptable as they were forced to retire both their cars with only a few laps to go.
"It was unacceptable behaviour by both drivers," she said when quizzed about the incident after the race yesterday.
"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."
