Barcelona's on-field celebrations following their 4-2 win over Espanyol, which confirmed the 27th La Liga title for Xavi Hernandez's team, were cut shot by angry Espanyol fans running onto the pitch to chase Barca players, who scampered back into the tunnel for safety.
Barcelona were celebrating on the pitch at the RCDE Stadium in Cornella at full-time, when around 100 Espanyol fans invaded the pitch.
