Carlos Sainz has emerged as a possible candidate for a Caterham Formula One seat. The Spanish driver's connection to Red Bull has made him a contender for the position.

What happened?

Carlos Sainz Jr., his father, and Helmut Marko visited the Caterham motorhome during the past weekend. This meeting has sparked speculation about a potential deal.

The visit suggests that Sainz Jr. is being considered for a seat at Caterham. Giving him race mileage now would be a logical step before a possible move to STR for 2015.

Why it matters for Carlos Sainz

Sainz Jr. currently leads the Renault 3.5 series after nine of 17 rounds. A senior Red Bull source stated that the company wants Sainz Jr. to focus on winning this series.

The Renault 3.5 series is a key championship for Sainz Jr. His performance in this series will be crucial for his future in Formula One.

What comes next?

Caterham has used a Red Bull gearbox and will be the only team using a Renault power unit alongside RBR and Scuderia Toro Rosso in 2015. This closer link between Red Bull and Renault could pave the way for Sainz Jr.'s move to Caterham.

The departure of Lotus to Mercedes for 2015 has allowed Red Bull to forge closer links with Renault F1's Viry base. Caterham is moving closer to RBR, which could lead to more opportunities for Sainz Jr.

In 2010, Red Bull placed Daniel Ricciardo at HRT in the middle of the season. This deal was brokered by Caterham advisor Colin Kolles. A similar move could be made for Sainz Jr.

Sainz Jr.'s experience and performance will be key factors in determining his future in Formula One. His connection to Red Bull and potential move to Caterham could be a significant step in his career.
