Horner says he sees no reason why Mark Webber would want to leave amid fresh Ferrari rumours

Webber has been mooted as a potential replacement for Felipe Massa at the Italian team next year - with some rumours suggesting that a deal is already done - but Horner said there had been no movement for 2013 yet, and that he felt Webber would be happy to stay put.

"Every spring seems to be a reciprocal thing that Mark is going to Ferrari," Horner told AUTOSPORT. "He is not wearing red overalls. I think it is inevitable, almost every driver in the pitlane has been linked alongside Fernando [Alonso] next year, but we are focused on ourselves.

"Mark enjoys being within the team, he is happy here and we are happy with him. At the relevant time later in the year we will sit down and talk about the future as we have done in previous seasons.

"It's something we will talk about later in the year. I'm not aware of any discussion. I think Mark is happy where he is, he is in a strong position here, but inevitably it's part of this business that there is speculation."

Although Webber has yet to take a podium finish in 2012, his pace relative to Red Bull team-mate Sebastian Vettel has been better than last season, and Horner expects that situation to continue all year.

"Mark has driven very well at the first few races," said Horner. "He has been settled in the car, turned up with a different approach this year which has been evident and he's in good shape.

"Four fourths... obviously we would dearly like to see him on the podium but they are vital points and he has driven very strongly. For sure he can put a very strong campaign together.

"I think it is good they push each other, it brings the best out of Sebastian as well. You want team-mates to keep raising the bar. There is a good dynamic between the two of them, they have pushed each other and the car hard, which is what you want."
