Former Red Bull boss Flavio Briatore does not believe that Mark Webber and Sebastian Vettel's partnership can continue into next season.
The pair's strained relationship was once more called into question at the weekend with Vettel ignoring team orders to pass Webber and claim victory in the Malaysian Grand Prix.
"I think there's no relationship anymore. It was already very formal beforehand between the two Red Bull drivers, that was very clear last year," Briatore told RAI Radio.
"Now Vettel says he will help Mark, but Mark doesn't need any help. He should have won the race, and it's possible that Vettel will win every other race.
"I don't think this relationship can be fixed. They are two professionals, they will win races and so on, but it's unthinkable that Mark may help Vettel in the future and I don't think Vettel will help Mark.
Webber's contract runs out at the end of this year.
