Schumacher wants help to catch Alonso

Schumacher trails the World Champion by 15 points after four races.

"I wish there would be a few other drivers up there fighting to win at the moment who could take some important points away. But it doesn't look like this is the case," the 37-year-old German told reporters on Friday.

Schumacher won last month's San Marino Grand Prix ahead of Alonso to make up two points on the Spaniard but at that pace it would take him eight victories to catch Renault's championship leader. There are 14 races left.

"I'm reasonably happy with the car," said Schumacher, who finished behind Alonso in Friday's afternoon practice.

"It looks like we'll be competitive. If we get everything 100 percent right, I think we've got a chance (to win)", the seven-times champion added.

Alexander Wurz was fastest in both Friday's sessions for Williams, but the Austrian test driver will not race on Sunday.

Alonso has finished in the top two in all Grands Prix so far this season and been on the podium for the last 10 consecutive races.

McLaren were expected to be in the hunt to challenge Renault's dominance but Kimi Raikkonen has only 18 points with one second and one third place to his name. His teammate Juan Pablo Montoya is on 15 points with one third place finish.
