Michael Schumacher celebrated the 20th anniversary of his Formula One debut by dominating the first practice session at Spa on Friday morning, with team mate Nico Rosberg backing him up less than half a second behind.
But the two Mercedes drivers were the only ones to venture out at the start of the 90-minute session, while the track was dry. They lapped in 1m 54.355s and 1m 54.829s respectively. Then, surprise, surprise, it rained.
