Big match winner became the club's 17-year-old superstar Lamine Yamal, who in the second half's opening scored a classy goal.
In his usual manner, he advanced from the right flank and beautifully curled the ball with his left foot up into the crossbar.
Barcelona could then hold off, thanks to a red card on Espanyol's Leandro Cabrera with ten minutes left of the match.
In added time, 2–0 would come through Fermín Lopez.
Thus, the club has secured its 28th league title in history.
Last time Barcelona won the league was two years ago – also then, they secured the title away against Espanyol. Then, Barcelona players were chased off the pitch by invading Espanyol supporters in connection with celebrating at midfield. On Thursday, it got rough between the teams – and the sprinklers were turned on to scatter the teams apart.
This season has been successful for Barcelona, as they have secured the domestic double with the league title. In April, the team won the Spanish Cup.
Thursday's derby against Espanyol was preceded by a car crash near the arena. According to El País, 13 football supporters were lightly injured. The match was interrupted but could be resumed after a short while.
