And Horner felt that the world was yet to see the best of Vettel, who will just keep getting better and better - news that will alarm his rivals on pit road.
“He will get better. He has every year and he is always so hungry to learn. What he has achieved at his age is remarkable,” he said. “Seb doesn't brag about it, he carries it modestly.”
But will that be with Red Bull? Despite constant denials from the driver and the team, all sort of rumours persist that Vettel has an arrangement to move to Ferrari
- possibly even as early as 2014.
“I can quite easily see him with us for another five years,” insisted Horner, once again brushing aside any suggestions of Vettel's departure from the team in the foreseeable future.
While Horner's clearly not keen on the criticism and barbed attacks coming Red Bull's way over recent weeks, he clearly views it as preferable to be on top with all the slings and arrows that come with it, than be everybody's best friend at the back of the grid.
“It is not something I am losing sleep over," Horner insisted.
