Seven-time world champion Michael Schumacher will step-up his preparations for a return to Formula One by getting behind the wheel of Ferrari’s 2007 F1 car this week — the official Formula One site has reported. The German will have a two-day test session at Italian circuit Mugello, starting on Tuesday, as he prepares to takes over from the injured Felipe Massa at the European Grand Prix in Valencia later this month. It follows the 40-year-old’s one-day stint in the two-year-old car, running on GP2 slick tyres, just over a week ago.
