13046 - Christian Horner hails Ricciardo and Vergne

Ricciardo and Vergne were announced as the new team drivers last month, replacing Sebastien Buemi and Jaime Alguersuari at the team.

"They are two of the most exciting talents on the periphery of F1," Horner told Autosport. "To put them in the same environment gives us a much better visibility in terms of seeing how they progress.

"They have done tremendously well in the lower formulas and in test and simulation work for Red Bull Racing and we are fully supportive of their promotion into the race seats."

Horner added that the former British Formula 3 champions could develop into future Red Bull Racing drivers over time.

"Those two guys are both very competitive. They are products of the Red Bull junior programme and are both Red Bull Racing drivers on loan to Toro Rosso to develop them.

"Time will tell. There are no guarantees. It's the best way to see how their talent evolves over the next season or so."
