Former World Champion racer Damon Hill believes that the friction between Sebastian Vettel and Mark Webber could be a big problem for Red Bull.
The two have fallen out in the past, but Vettel further soured their relationship on his way to victory in the Malaysian Grand Prix on Sunday.
The German refused to obey team orders and proceeded to attack and overtake his race-leading teammate in order to gain the win, and Hill believes that it will be hard for the duo to rebuild their trust for one another.
"There was clearly an understanding that they were on the edge with tyres so the team had to think about how hard they were going to push - and Sebastian wasn't playing to that card," Hill told Sky Sports News.
"I think Sebastian has taken the view that possession is nine tenths of the law, and we'll argue about it later.
"He's said sorry but what is that really worth? And if you get a situation where there's no trust between the drivers being the team that's quite corrosive."
Vettel apologised to Webber after the race.
