Red Bull boss Dietrich Mateschitz has insisted that talk about the team's driver line-up ✨for the 2014 F1 season and beyond is 'pure speculation'.

Rumours about the line-up have increased in the aftermath of the Malaysian Grand Prix, with suggestions that Sebastian Vettel's decision to ignore team orders had made it impos🦩sible f🌸or the defending champion and team-mate Mark Webber to remain together next year.

The team has already moved to state that it was too early to discuss its 2014 pairi🦩ng, with Mateschitz reiterating that fact and insisting that everything was still open in regards to n🦩ext year.

"Mark is definitely a candidate for 2014," he told Speed Week. "Whether he retires, only he would know.

"With us, he is always welcome, just as a quick junior like Vergne or Ricciardo from the Toro Rosso team would be. Sorry, that is not a diplomatic answer, which leaves everything open, but♕ that's how it is. Everything else is pure speculation. "
