We shall see how this season goes - Schumi -8th January 20:15pm GMT

Ferrari's Michael Schumacher says he will make a decision on his Formula One future midway through the 2006 season.

"If I don't have the chance to win races and challenge for the title I don't think I'll be very keen to extend my career," the 37-year-old said in an interview released on Saturday by German magazine Der Spiegel.

"If we want to progress we need more staff (at Ferrari). In Formula One you cannot afford to stand still. I want to know where we're heading." Schumacher's contract with Ferrari expires at the end of 2006.

The German, seven times world champion, managed just one race win last season.

He finished third in the standings, well adrift behind Fernando Alonso of Renault and Kimi Raikkonen of McLaren and described the season as "catastrophic".

"After all the successes, carelessness crept in," he said.
