Rubens Barrichello will not be returning to F1 with Sauber next season after Monisha Kaltenborn revealed that they have "never discussed a seat."
Last month reports emerged claiming that Barrichello was plotting a return to Formula One next season with the Sauber team.
And although Kaltenborn initially played along, the Sauber team boss has now categorically ruled out signing the former Ferrari driver.
Asked whether the Barrichello rumours were serious, Kaltenborn told PA Sport: "No.
"I have a lot of respect for Rubens, and I don't think it is right I abruptly say 'no, we are not going to talk'. I have to be respectful to such a driver.
"I fully understand he wants to drive and he is trying his best.
"I talk a lot with him when he is here, we discuss young drivers and so on, but we have never discussed a seat. That's reality.
"It's a bit unfair towards him because it doesn't look good for him. So, just to be very clear on it, we have not discussed a seat for next year and also no drive for Brazil."
She added: "I am ruling out he will drive for us. Maybe it is better one is that clear about it.
"I just felt it would be a bit rude to do that. I was trying to be nice on it."
