The former Formula One team boss Flavio Briatore believes feuding team mates Mark Webber and Sebastian Vettel will not stay together at Red Bull after this season.
Briatore, the former Renault team boss who has been part of Webber's management throughout his grand prix career, says he spoke to Weber after the controversial Malaysian Grand Prix.
He says Webber is still furious with triple world champion Vettel winning at Sepang after ignoring team orders and overtaking him in the closing laps.
Briatore says he doesn't think the relationship can be sewn together again and there have been problems for a while.
Webber, who will be 37 this year, is out of contract at the end of the season while Vettel is tied to Red Bull until at least the end of 2014.
He and Vettel have had several flare-ups since the start of their pairing in 2009, including a collision at the 2010 Turkish Grand Prix that cost Webber a victory and sent the German out of the race.
Webber has long maintained that the team favours Vettel, despite their insistence that the two have equal status.
