Takuma Sato believes only a large slice of luck will deliver a grand prix victory to his team BAR in the short term.
BAR have had a promising start to the 2004 season and are currently third in the constructors standings behind Ferrari and Renault with the Canadian Grand Prix to come this weekend.
Despite Sato's English team-mate Jenson Button appearing on the podium five times already this year, he has failed to reach the top step with Sato's best finish being fifth in both Bahrain and Spain.
Sato told BARf1.com: "Winning a Grand Prix is very difficult, very tough. Although we are challenging Ferrari a lot closer than we were last year there is still a significant gap between us and we still have to close the gap first.
"Once we are ready to race side-by-side with them then we can think about winning.
"But to win a Grand Prix now, I think we need a lot of luck, otherwise it is probably very difficult."
