Red Bull advisor Helmut Marko has claimed that McLaren driver Lewis Hamilton is always a 'topic' for the team.
At present, only Sebastian Vettel has been confirmed at Red Bull beyond the 2011 season, as Mark Webber may have begun his final year with the current World Champions.
Hamilton still has a few more years left on his contract with Woking based McLaren, but has recently emphasised that he does not want to win just one World Championship (separate story - click here)
However, Red Bull chief Christian Horner has denied Marko's claims, suggesting that Vettel and Hamilton's personalities may clash if they drove for the same team.
Vettel and Webber infamously clashed on and off the track during the 2010 campaign, and Hamilton had a fiery relationship with his team mate Fernando Alonso in Hamilton's debut season. It is therefore not surprising that Horner would be concerned that the two drivers - who were both the youngest ever World Champions at the time they won - would not compliment each other.
However, Horner didn't completely rule out a future move.
"If he wanted to drive for Red Bull then of course you couldn't ignore a driver of his calibre."
