Red Bull team principal Christian Horner has dismissed speculation that Mark Webber will leave the outfit at the end of the season.

Reports have linked the Australian driver, who won Sunday's Monaco Grand Prix, with a move to Ferrari for the 2013 campaign.

The Italy-based team are apparently losing patience with Felipe Massa, who has picked up just 10 points from the opening six races.

However, Horner has denied the rumours and insisted that there is no reason for Webber to leave Red Bull for another team.

"Why would he want to leave?" said Horner. "He is comfortable in the team. The team know Mark very well and he knows the team very well."

Red Bull currently lead the constructors standings by 38 points from McLaren.
