Red Bull team principal has dropped his broadest hint yet that Mark Webber will be staying with the team for the 2012 Formula 1 season.
Webber has yet to sit down and begin contract negotiations with Red Bull but he has recently expressed his wish to extend his rolling deal by another year.
Horner has refused to discuss the situation until now but he has admitted he would like to keep the Australian for at least another year.
"Well, that's very, very likely," Horner told Servus TV when asked about Webber staying on at Red Bull. "We have agreed to sit down a bit later and then focus on next year."
Horner was spotted deep in conversation with Lewis Hamilton at the Canadian Grand Prix, a meeting that prompted speculation linking the Briton with Red Bull.
Hamilton moved quickly to end the rumours and Horner is in no doubt that the former world champion will not be on the move anytime soon.
"I really don't think blue is his colour," Horner said of Hamilton.
"For Red Bull, the most important thing is the harmony."
