Oct.15 (GMM) A former German formula one driver has criticised Ferrari for not designating a clear 'number one' in the post-Michael Schumacher era.



Michael Bartels, who failed to qualify for four races with Lotus in 1991, thinks the Italian team would have had a better chance of winning the title in Brazil this weekend if either Kimi Raikkonen or Felipe Massa had started the year as the team's preferred driver.



He told the news agency Sport-Informations-Dienst that if Kimi is not crowned at Interlagos, he can blame Ferrari for employing "the wrong tactics".



Raikkonen and Massa's equal status in 2007, unlike Schumacher's clear role as number one in the past, has meant that the pair have taken points off one another all season.



"You can easily calculate the points that Ferrari has wasted because they did not have a number one driver," Bartels, 39, said.
