Mercedes boss not blaming Schuey

Mercedes team boss Ross Brawn has exonerated Michael Schumacher of any blame for the spate of retirements which have wrecked his season.

For the fifth time in seven races on Sunday Schumacher failed to see the chequered flag, raising further questions as to whether this will be his last campaign before retiring for a second time.

In the Canadian Grand Prix, a hydraulics issue with his DRS wing, used for overtaking, in an open position, resulted in his fourth mechanical retirement this year.
