Carlos Sainz Jr. has emerged as a possible candidate for Caterham, thanks to the Formula One team's relationship with Red Bull, and a deal has been discussed for the Spaniard to race for the team this season.
Sainz Jr., his father and Helmut Marko were seen paying a visit to the Caterham motorhome during the course of this past weekend.
Giving Sainz some race mileage now, prior to a possible move to STR for 2015, would be a logical step. However, a senior Red Bull source said that in the short term the company wants Sainz Jr. to focus on winning the Renault 3.5 series, which he currently leads after nine of 17 rounds â although none of the remaining races clash with the F1 calendar.
Caterham has long used a Red Bull gearbox, and next year it will be the only team using a Renault power unit alongside RBR and Scuderia Toro Rosso. The departure of Lotus to Mercedes for 2015 allows Red Bull to forge closer links with Renault F1â²s Viry base, and Caterham is in turn moving closer to RBR.
It's worth remembering that in 2010 Red Bull placed Daniel Ricciardo at HRT in the middle of the season, in a deal brokered by Caterham advisor Colin Kolles
