Germany's Ralf Schumacher has ruled out of the race to become Lewis Hamilton's new team-mate at McLaren.   Schumacher, the younger brother of seven-times world champion Michael, left Toyota at the end of the season without announcing his plans for 2008. The German's manager has since approached McLaren about the position vacated by Fernando Alonso, according to The Guardian, but "it was quickly made clear he would not be on the list". McLaren say they are in no rush to find a replacement for double world champion Alonso and have already been approached by a number of drivers. "Until the second McLaren drive is sorted out I don't think you'll see much movement [in the driver market], so obviously we're not really hurried," said McLaren Chief Executive Martin Whitmarsh. "Obviously there are some drivers who've approached us who are contracted elsewhere and we've had to say we can't talk to them unless they can prove they are free to negotiate." Favourite to fill the position is Nico Rosberg, despite the German being contracted to Williams next season, while Finland's Heikki Kovalainen and German rookie Adrian Sutil have both been linked with the position. McLaren can also fall back on experienced Spanish test driver Pedro de la Rosa, who last raced for the team in 2006 as a replacement for Colombian Juan Pablo Montoya and finished second in that year's Hungarian Grand Prix.

Haha, well, you must admire the optimism and courage to ask at all, but I believe the answer was no surprise to anybody.

Keep dreaming, Ralf - you're history ! Just like big bro
