Daniel Ricciardo has said that he is upbeat about the chances of Red Bull getting over their reliability problems before the start of the Formula 1 season.

Ricciardo and world champion Sebastian Vettel managed just 21 laps between them at the first test in Jerez this week.

He told reporters: "Obviously now it's good to have a bit of a break before Bahrain, take it all back to the factory and figure it out, and look forward to doing a few more laps there.

"As we expected it's going to take a bit of time, so we'll go back and hopefully figure it out before Melbourne."

Red Bull have won the constructor's title for the last four years.
