With Mark Webber leaving Red Bull at the end of this season, his seat at Red Bull has been the topic of many a heated debate.

Until now, the seat has had three names on it – Kimi Raikkonen, Daniel Ricciardo and Jean-Eric Vergne.

In an interview with Sky Sports today however, Christian Horner has indicated that it is not likely that Jean-Eric Vergne will get the seat saying that we’re “probably” looking at a two-horse race now.

Vergne had already been shifted aside with the Young Driver Test this week, since Red Bull have given Daniel Ricciardo an opportunity to drive the RB9 at Silverstone, rather than using Vergne.

When asked whether the choice is now between Ricciardo and Raikkonen, Christian Horner replied, “Essentially, probably.”

Talking to Sky Sports, he explained the rationale behind using Ricciardo for the Young Driver Test. “We’re very keen to have a look at Daniel as a prospect for next year. Obviously there is a great deal of interest in the seat, but it’s an opportunity to have a look at Daniel and for him to do some of our tyre testing work in our RBR car. It’s a great opportunity for him.”

Ricciardo does seem like a safer bet than Raikkonen since he’s less likely to ruffle the feathers of remaining Red Bull driver, Sebastian Vettel. Raikkonen however, is likely to be a force to be reckoned with in the Red Bull so it’s going to be a tough choice for Horner and co.
