Michael Schumacher believes rival David Coulthard is lucky to be in with a chance of the championship and is only in the hunt because of his consistent finishing record.
Coulthard failed to finish for the first time this season in last weekend's Canadian Grand Prix, but has benefited from an impressive run of reliability from his McLaren team.
"David has been honestly lucky this year," said Schumacher, who lies 18 points ahead of the Scot. "He has always been in the points and although he has struggled with the pre-start situation twice, a zero point (in Canada) was the first time and that is pretty unusual."
Coulthard suffered his first failure to finish this season in the last race in Canada and his luck could be turning for the worse, but Schumacher is not seeing that as a chance to take it easy.
"I believe after Imola people thought the same about me," said Schumacher. "Now I am back - but I am not comfortable at all. I believe that the main rivalry is between Coulthard and myself, but even though I am roughly 30 points ahead of Ralf it can still mean that he is able to win the championship. It is far too long to be over."
