Ralf Schumacher believes he is one of the top three drivers in Formula One. In an interview with Bild newspaper, Schumacher ranked himself alongside F1's undisputed top two Fernando Alonso and Kimi Raikkonen. "Clearly they are really fast but I don't feel like I have to hide from anyone," he said. "I rank myself among the best three drivers. If I didn't think that then I wouldn't bother being in Formula One any more." Schumacher looks set to be buried in the midfield this year with Toyota's so-far uncompetitive TF107, admitting that it is presently at least a second per lap slower than the leading bunch. He explained: "But in a slow car even my brother wouldn't have been World Champion."

I am afraid he isn't joking - he seems to believe this rubbish himself. I can think of about 20 drivers who are better than Half
