Williams must get their act together in Malaysia next week if they are to keep up with Formula One champions Ferrari, according to their technical director.
"I'd be very disappointed if we didn't do a lot better in Malaysia than we did in Australia," Patrick Head said.
"Clearly if we allow a situation to perpetuate where Ferrari are finishing first and second, even if we finish third and fourth, Ferrari will start opening up a big gap in the
constructors' championship.
"We can't afford for that to happen so we need to get our act together pretty quickly and start scoring points."
Ferrari romped to a one-two finish in the season-opening Australian Grand Prix last weekend with six times world champion Michael Schumacher leading from pole to chequered flag in a
dominant performance.
Williams, who are aiming to wrest the title from the Italian team this year and had high hopes for their new car, saw Ralf Schumacher finish fourth and Colombian Juan Pablo Montoya a disappointing fifth.
Head said the BMW-powered team's performance in Melbourne had not been good enough and they were developing the car as fast as they could.
