Barcelona have set a new La Liga record of 39 consecutive games unbeaten thanks to Saturday's 2-1 win over Valencia.
Luis Suarez opened the scoring at Camp Nou on 15 minutes when he picked up Philippe Coutinho's threaded ball and side-footed past Neto at the right-hand post.
Valencia responded well to falling behind and enjoyed numerous opportunities to get back into the game, with Goncalo Guedes and Rodrigo Moreno coming close on several occasions.
However, Los Che could not get the ball over the line and were punished when Samuel Umtiti then doubled the hosts' lead on 51 minutes, heading home Coutinho's corner.
Valencia did manage to halve the deficit three minutes from time, Ousmane Dembele carelessly bringing down Jose Gaya for a penalty which Dani Parejo slotted beneath Marc-Andre ter Stegen.
However, Barca hung on to secure all three points and, with victory, break the Spanish top flight's unbeaten record in style.
Real Sociedad previously held the record, notching up a 38-game unbeaten run from April 1979 to May 1980.
