Real Madrid responded in style to Barcelona's record breaking, 16th consecutive league victory with Cristiano Ronaldo leading the way in a 4-1 win over Real Sociedad on Sunday.
Ronaldo was charged up for the game after being criticised for not scoring in four matches and having seen Lionel Messi hit a hat-trick in Barcelona's 3-0 win over Atletico Madrid on Saturday.
That victory saw Pep Guardiola's side surpass the run of 15 victories set by Alfredo Di Stefano's Real Madrid team of 1960-1961 and put them ten points clear at the top.
Real, with Emmanuel Adebayor given a starting place after his goal in the Copa del Rey against Sevilla in midweek, pressed forward from the start with the visitors encamped in their own penalty area.
Sociedad were nervous in possession and a poor clearance from Gorka Elustondo fell to Kaka and the Brazilian slotted the ball into the corner after just seven minutes.
Before half-time he powered home a header from a corner to notch up his 25th goal of the season and retake the lead in the goal-scoring charts from Messi.
