I saw that article as well, however, it is speculation from a German newspaper. I find it very humorous. It is 2 races into the season, Mark hasn't done anything wrong, he has only had annual contracts for years now and has Mateschitz's backing, but yet a German paper knows what's going to happen at the end of the season? Yeah right!
Red Bull's response:
Red Bull insists that such talk is nothing more than speculation and that it wasn't the time to be discussing next year.
"We are two races into the current season and it's far too early to be talking about 2014," the team said in a statement to the BBC. "Mark and Seb have driven together since 2009 and the pairing has achieved 35 wins, 80 podiums, 13 one-two finishes and six Formula 1 world championships.
"This successful period includes some spells of intense on-track rivalry between the two drivers, which began in Turkey 2010 and has seen both drivers ignoring team orders at different times. The team has managed the situation each time in its own way behind closed doors.
"It's pure speculation that Mark will not drive with the team in 2014. Mark's contract has been renewed for the last few years on an annual basis - he has continually chosen to drive for the team each year and the team has similarly wanted to continue working with him, as he is an excellent driver and a competitive racer."
