Michael Schumacher can help steer Ferrari to a sixth consecutive constructors' Formula One world championship at his home German Grand Prix this weekend. If he and teammate Rubens Barrichello finish one-two at Hockenheim, even clean-sweep victories for Renault to the end of ཀ could not usurp the Italian team. Asked if he thought Ferrari will tie it up, Michael said "Possibly." "It's going to happen sooner or later, to be honest." The 35-year-old racer, himself a six-times world champion, said winning the carmakers' title at home would spark a 'very big party' at the circuit. "It's difficult to avoid winning the constructors' title [now]," Schumacher added. The German is now listing McLaren's &#039B' car as a real threat to race victories. "Wait and see," said Schumacher, "but don't forget about us."
