Tensions flared within the Formula 1 team when world champion Vettel disobeyed team orders by overtaking Webber to win the Malaysian Grand Prix.
"Obviously it's been strained, the relationship, it's not the first time," Webber told Sky Sports News. "Let's see how it goes in the future. At the moment we'll focus on our own individual performances and go from there."
Meanwhile, Vettel has revealed that if the opportunity arose again he would overtake the Australian.
