With Marussia and Caterham still fighting it out for tenth in the 2013 F1 Constructors' Championship the opening day at Abu Dhabi showed once again that there is little to choose between the teams.

Jules Bianchi trailed Giedo van der Garde by three tenths of a second following second practice at the Yas Marina Circuit but speaking exclusively to Crash.net the Frenchman said he was pleased with his efforts.

"Today was positive and FP1 was good and we were in front of Caterham on the first run but then they improved," said the French rookie. "In FP2 we tried to tune the car and it was working well. We were competitive with Caterham again and the long run was also OK but we had an issue with the setup. [Overall, though] I'm really happy with the day."

When pressed as to what was the issue that Bianchi was suffering the 24-year-old admitted that he was suffering from understeer. With so many slow speed and 90 degree corners in Abu Dhabi understeer costs a driver dearly.

"We had a balance issue, mostly understeer, which is a bit difficult at a track like this because you need to carry entry speed," he explained. "When you have understeer you cannot because you have to stop the car and you lose a lot of time. Hopefully we can tune that out tomorrow. In the faster corners we are OK but the main issue was in the slower speed corners."

With Marussia holding the edge in the Constructors' Championship, courtesy of Bianchi's 13th place finish in Malaysia, it is difficult to see Caterham overhauling their rivals and when asked about the fight between the teams this weekend Bianchi added: "It's difficult to say [who is best] because we don't know what fuel level they were running.

"But we are looking competitive. Maybe they are running more than us but it's looking good," he concluded.
