While the Australian's team had a nightmare first week with its 2014 F1 car, Mercedes racked up the miles at Jerez and even managed to complete a race-distance simulation.

Ricciardo insists, however, that Mercedes' early form does not worry his team - especially because no one has shown their full potential so far.

"I don't think it adds pressure," said Ricciardo of Mercedes' achievements in Spain.

"For all we know they could be racking up a lot of laps, but they could be a second off the pace - who knows? We are not going to read into it.

"We would have loved to do more laps, I came to drive, but there you go."

Although Red Bull's overheating and power unit problems meant Jerez was a huge disappointment, Ricciardo thinks the two-week gap before the next test in Bahrain should give it time to get on top of its issues.

For while efforts at the track to remedy Red Bull and Renault's troubles did not work - with the team managing just 21 laps in total over four days - he thinks factory efforts for more permanent solutions will be more successful.

"It is complex," he said about the issues that the world champion team faced. "It is a combination of more or less everything.

"It is such a complex system this year that it is not going to take 24 hours to solve.

"I think it is best now that we get some time away from the track and figure out what needs to be done.

"It is not my job; I will be keeping in touch with the team over the next few weeks and seeing how it has all gone."
