Red Bull team principal Christian Horner has written off Lewis Hamilton's chances of joining his marque from next season.
Despite his problems last year, Hamilton's talent is undeniable and he could find himself a wanted man over the next few months with his contract with McLaren due to expire at the end of this season but seemingly not by Red Bull where a vacancy may loom as the feeling is this season will be the 35-year-old Mark Webber's last.
"It's difficult to envisage Lewis in our team," said Horner.
"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've two really exciting youngsters entering GP racing in Jean-Eric Vergne and Daniel Ricciardo.
"Both are really talented drivers and deserve that opportunity. It will be fascinating to see how they evolve over the year. So we're more likely to look inwardly than outwardly."
The feeling is a Vettel-Hamilton partnership would not work given both men are particularly strong characters.
"You have to look at the balance within the team as well," added Horner.
"It is important to have the right balance within any team, not just with the drivers, but throughout the organisation. Whether or not it could work, who knows?
"But our preference would probably be to go with drivers in whom we have invested from a young age, give them the opportunity and see how they evolve rather than take something external."
