Red Bull's principal Christian Horner has dismissed speculation that Lewis Hamilton could join his team next season.
The British driver is out of contract with McLaren in the summer, leading to reports that he could link up with world champion Sebastian Vettel at Red Bull.
However, Horner is adamant that he is happy with the current driving talent that is at his disposal.
"I think that it's difficult to envisage Lewis in our team," Horner told the Daily Telegraph.
"I think he's comfortable in the environment he is in and we're certainly comfortable with the two drivers we have.
"We also took a decision to invest in youth and we have two really exciting youngsters entering grand prix racing in Jean-Eric Vergne and Daniel Ricciardo - both really talented drivers and both deserve that opportunity. So we're more likely to look inwardly than outwardly."
Red Bull will begin the defence of their world title this weekend in Australia.
