Atletico Madrid striker Radamel Falcao struck a hat-trick in victory over Real Sociedad.

Club-record signing Falcao opened the scoring from the penalty spot in the third minute and, after Adrian Lopez had doubled Atletico's lead just after half-time, the Colombia international completed his treble with two more goals late on.

The victory ended Atletico's miserable away run and continued the impressive start made under new coach Diego Simeone, whose first three games in charge have now yielded seven points, with seven goals scored and none conceded.
