Barca continued their perfect start to 2017-18 Liga campaign by comfortably disposing of Espanyol by 5-0.
Barca was once again carried by their talisman Lionel Messi who scored his first hat-trick of the season and took his overall tally in Catalan derbies to 18 goals.
Messi opened the scoring in the 25th min when he slotted home an Ivan Rakitic pass from a slightly offside position. The Argentine was then twice assisted by Jordi Alba and claimed the match ball in the 67th minute.
Crowd favourite Gerrard Pique added a 4th from Ivan Rakitic’s corner in 87th min followed by an impressive assist by record signing Ousmane Dembele to set up Luis Suarez for the 5th.
Barca has now extended their lead over defending champions Real Madrid to 4 points after Los Blancos could only manage a draw against Levante at the Bernabeu earlier.
