Watch! Sea of fans celebrate as Barcelona end title drought to win 27th La Liga title

Hundreds of Barcelona fans celebrated Sunday at Las Ramblas as the Catalan Giants ended their 3-year title drought by winning La Liga for the 27th time.

Barca beat Espanyol 4-2 to clinch their first Spanish league title since the departure of Lionel Messi two years ago. The title was secured with four rounds remaining amid the club’s financial struggles.

Barcelona players also celebrated the moment on the field but the celebrations were short-lived. Barca players had to rush into the locker room after a large group of Espanyol fans invaded the field from behind one of the goals and started running towards Barcelona players who were singing and celebrating in the center.

Security guards quickly intervened but riot police had to stand in front of the tunnel’s entrance to prevent the fans from going in.

Speaking about his team's title joy being halted by rival fans, head coach Xavi Hernandez said that his side celerated the win inside and didn't want to give too much importance to the crowd invasion.
