Christian Horner says Red Bull's driver pairing of Daniel Ricciardo and Max Verstappen is "very healthy" and is helping the team achieve its goals in 2016.
There had been initial question marks over whether the driver line up would cause friction at Red Bull but Horner reckons the team has only benefitted from having two competitive drivers in its ranks.
"You can see that it is very healthy," said Horner. "There is great respect between the two of them. As far as teammates can go, they seem to like each other and they want similar things from the car. Beyond that, they're both very, very fast.
"[Germany] went in Daniel's favour, Barcelona went in Max's favour -- it's the swings and roundabouts of a season, and I think that both drivers have done an outstanding job."
Red Bull moved 14 points clear of Ferrari in the constructors' standings going into the summer break thanks to a double podium at the German Grand Prix. Hockenheim also marked the third consecutive circuit that Red Bull has beaten a Ferrari driver to the podium.
With the team engaged in a direct battle with Ferrari over second place in the championship, Horner believes Red Bull's recent form is a positive sign for the remainder of the season.
"We've had great performance from a variance of circuits, from Austria to Silverstone to Budapest and, [Germany] -- four very different venues, with very different surfaces -- and I think that bodes well for the second part of the season."
