Alexander Isak was the star of the show on Sunday as Real Sociedad cruised to a 4-0 win over Alaves. 

The Sweden international finished the game with a hat-trick, becoming the youngest player in the San Sebastian club's history to score three goals in a single LaLiga game.  

Earlier in the game, the 21-year-old equalled another club record by scoring in a sixth LaLiga game in a row, joining John Aldridge and Darko Kovacevic to become just the third La Real player to do so.
