Schumacher untroubled by Button challenge

Jenson Button’s hopes of putting a spoke in the wheel of Michael Schumacher’s bid for a seventh Formula One world title foundered inside 11 laps of the San Marino Grand Prix.

The daunting Schumacher eventually clinched a comfortable fourth win of the season to maintain his 100% record, giving the Ferrari star a maximum 40-point haul, extending his lead in the so-far one-sided championship to 16 points to team-mate Rubens Barrichello.
