No big Williams update until Monaco

The first European race of the season at Catalunya in ten days' time is set to see a huge number of new developments on the cars as teams make the most of being back on their home continent after four flyaway races, and of having a three-week break since Shanghai.

But Williams technical director Sam Michael said his team planned to bring its new parts later.

"We do have some stuff for Barcelona, and that's a good step, but I think the bigger steps will come for Monaco and Istanbul," he said.

Despite looking strong in the final pre-season tests Williams is currently only seventh in the constructors' championship with Rubens Barrichello's eighth place in Australia its best result of 2010.

However Michael remains confident that the FW32 has good potential that just needs to be extracted.

"We've made a lot of changes, so it's taking time to get us a little bit more up to speed," he said.

"We've got a good development programme for the car and a lot of stuff coming through in the next couple of races - Monaco and Istanbul.

"We'll just keep our head down and try and get that stuff on the car as quick as we can."
