Barcelona claimed their 27th LaLiga title on Sunday after two first-half goals from Robert Lewandowski spurred them to a 4-2 thrashing of 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.
Barca were the superior side against lowly Espanyol who are second from bottom and fighting to avoid relegation and opened the scoring early with a close-range strike by Lewandowski.
Alejandro Balde, who put it on a plate for Lewandowski's opener, scored Barca's second with a tap-in from a Pedri cross in the 20th minute.
Lewandowski extended Barca's lead five minutes before the break with another close-range finish from a Raphinha cross.
Defender Jules Kounde headed in Barca's fourth in the 53rd minute, before Javi Puado and Joselu scored consolation goals for Espanyol.
