One more Schumacher rumor

(GMM) Mercedes boss Norbert Haug has described at Monza the intrigue surrounding Michael Schumacher's looming future as a 'mystery'.

Every possible scenario, including sabbaticals and retirement, has done the rounds in the picturesque setting for the Italian grand prix so far this weekend, but it is worth mentioning one more rumor.

It is suggested that the 37-year-old Ferrari driver could announce his departure from the team on Sunday afternoon, before returning to formula one in a silver car in 2008.

''There is nothing new to report,'' Haug insisted to German pay-TV broadcaster 'Premiere'. ''Such things do not have any substance.''
