Former chairman Adam Parr says he feels Williams can bounce back from its difficult start to the 2013 F1 season when the European leg of the campaign gets underway this weekend in Spain.

The Grove-based outfit has yet to score this season, leaving it as one of only three teams alongside Caterham and Marussia to have a zero score going into the Catalunya race.

While the first European race of the year proved to be the highlight for Williams last year after Pastor Maldonado secured a surprise victory, there is little chance of such a repeat this time around, although Parr said he was sure that his former outfit would soon turn the corner.

"I know they've got the ability to get on top of these problems," he told Sky Sports. "The head of aero, Jason Somerville, Mike Coughlan and Ed Wood, the Chief Designer, are talented, capable people.

"They did a great job with a great car last year. This year's car is only an evolution; possibly, maybe, they're trying to be too complicated?

"I'm completely confident that Barcelona will see them take a step forward and if you look at how the boys raced in Bahrain, of course they weren't in the headlines, but eleventh and 14th - they made up positions and had a solid race. If they do that in a slightly better car, they'll start building up points."

Prior to his departure from the team, many had tipped Parr to one day replace Sir Frank Williams at team principal but he insisted that that was never part of the plan - with Claire Williams being seen as the long-term replacement for her father.

"My plan was always Claire," he said. "I worked with Claire from the day I started. She worked her way steadily through the business on merit and I was proud and pleased to promote her to the board along with another woman, Louise Evans, who is the finance director.

"I think Claire has all the makings of being a great team principal for Williams. My only regret is that I intended to be there a little bit longer to help her make the transition and support her in that process. But I never wanted to be a team principal."
