Real Madrid strolled to a 4-1 victory over struggling Real Sociedad yesterday to briefly lead the Spanish first division before Valencia's 2-1 win over Osasuna.
First-half goals from Guti and Fernando Hierro, a superb strike by Luis Figo and a fourth by Savio sealed a comfortable first away win for Real Madrid.
Later Valencia struggled to a barely deserved victory over a highly motivated Osasuna side to move two points clear at the top. Osasuna went ahead through Jose Manuel Mateo after six minutes but Valencia clawed their way back with an own goal from Cesar Cruchaga and a late strike by Norway's John Carew.

Real Sociedad, with new coach Periko Alonso making his debut on the bench, began in enthusiastic fashion, pushing forward in midfield. But the optimism of the home crowd was short-lived when Guti claimed his fifth league goal after 13 minutes. Fernando Hierro converted a spot kick to make it 2-0 in the 42nd minute and a minute into the second half Figo added a third.
Savio completed a miserable day for Alberto when his 62nd minute shot found its way through the goalkeeper's legs.
