Williams BMW technical director Patrick Head says he’d prefer Michael Schumacher over any of his current drivers. But would the FW25 win races even if the German was driving it?

Ralf Schumacher and Juan-Pablo Montoya have won a total of five grands prix for Williams BMW in the previous two F1 seasons, but few F1 observers doubt that Sir Frank’s team would snap up the five-times world champion if Ferrari ever lost its grip on him.

Head told on Tuesday that although he was more than happy with Ralf and Montoya, the world champion’s services would be an offer not to be refused.

“You'd have to say, and let's be honest about it, if every team was asked what driver they most wanted, they would say Michael Schumacher," Head was quoted as saying. "They probably wouldn't want to pay his salary - or couldn't afford to pay it - or keep up with the car's developments he would expect. But the fact remains that everyone would want him."

"I am happy with our two drivers, Juan Pablo Montoya and Ralf Schumacher, and I wouldn't want to change them - unless someone came along and said: 'Here's Michael'," Head added.

But would the addition of Schumacher to Williams BMW’s ranks make any difference to the FW25’s victory chances?

F1 fans around the world are wondering whether Williams BMW’s 2003 car is the metaphorical “diamond in the rough” or an aerodynamically-inefficient car that will struggle to keep up with McLaren Mercedes and Ferrari once the Woking and Maranello-based squads launch their new cars later this season.

Williams-BMW star Juan Pablo Montoya has admitted he is clueless about whether his car will be quick enough to allow him to contend for victory in this weekend's Malaysian Grand Prix.

The Colombian recently told that although Williams BMW was historically strong around the Sepang circuit, the new FW25 chassis might not continue that trend.

"It is pretty difficult to say how we will perform in Malaysia," said Montoya. "We might be really good or we might be 10th! Barcelona is the only fast track we tested on over the winter and we haven't been very quick there. On the other hand, we have historically always been really quick in Malaysia."

He added: "Sepang is a very smooth track and last year we had our first and only one-two finish there. I think the hot weather should suit our package. Considering the improvements Michelin have made, I am not concerned about the rain."

Head said: "We are encouraged by the last race performance of the FW25 and we have made further tests, yet we appreciate that we still have a lot of hard work ahead of us."
