"I don't maintain we're perfect, but I suspect we're one of the least political teams internally in the pit lane."
BMW-Williams have dismissed the concerns of their driver Juan Pablo Montoya that he may be suffering because of politics within the team.
Montoya has hinted that he feels Ralf Schumacher has more influence in the team than he does, and says this is particularly the case with engine supplier BMW.
The Colombian is in his first season in Formula One.
And, while he has impressed with some startling drives, he has in general struggled to match Schumacher for absolute pace, particularly in qualifying.
"Ralf is in his fifth season of F1, and his fourth of using grooved tyres (which are not used in any other motor racing category), so it would be wrong to expect Juan Pablo to be as astute as Ralf in making judgements about the set-up of his car," Head said.
"The media are looking at Juan Pablo as the new messiah, a man who will take it to Michael Schumacher.
"Certainly he has that level of ability, but it is a pretty high expectation of him.
"Juan Pablo won everything in his first year of Cart (Montoya was champion of the US-based series in 1999).
"He doesn't come here expecting to learn. He wants to be on the front row at every race. That's the level of expectation he puts on himself.
"I don't maintain we're perfect, but I suspect we're one of the least
political teams internally in the pit lane."
Head said that he believed Montoya was "a bit concerned" by the close relationship between Schumacher and the team's new chief engineer, Sam Michael, with whom the German has previously worked at Jordan.
But he dismissed Montoya's worries.
"I don't believe we are doing him down in any way - and nor are BMW."
Head did add, though, that the team would naturally give the best available engine to Schumacher while he was proving to be the quicker driver.
"In most of the races, from early on in the practice sessions, Ralf has been the driver closer to the front," he said.
"BMW build their engines in the same way, but they actually put them on a performance-measuring machine.
"And do you tell the driver that one engine has one horsepower more?
"But I happen to know that the engines are being very evenly and fairly distributed this year."
BMW motorsport director Mario Theissen said: "To a certain extent I understand what he [Montoya] said, because it takes time to build a relationship with a driver.
"But it's certainly not that one driver would have an advantage from us."
