Mercedes continue to rule the roost, with one or other of their drivers leading all three free practice sessions. Pole position may be important at Hockenheim, but with the weather forecasts still suggesting rain for Sunday, it may be more of a lottery than a procession. Still, Rosberg will be looking for pole at his home race, whilst Hamilton will be looking to stop him. And further back, McLaren have shown increased pace, Ferrari want to improve, and Williams aim to continue their success. It's all to play for as the hour of reckoning awaits - who do you think will get into the top ten today?
