Barcelona claimed their 27th LaLiga title and first for four years on Sunday after two first-half goals from Robert Lewandowski spurred them to a comfortable 4-2 victory over city rivals Espanyol.

Barca moved to 85 points from 34 matches and extended their lead to an unassailable 14 points over second-placed Real Madrid.

There was little time for jubilation, however, as the visitors had to quickly rush off the pitch after fulltime as several Espanyol fans invaded the field as Barca started to celebrate their title.
