Celta Vigo suffered a Valentines Day massacre losing 6-1 against Barcelona at the Camp Nou.
Barcelona broke another record extending their unbeaten record under the command of Luis Enrique to 30 games.
Barca have also now won all nine games Arda Turan has featured in this season following his debut in the 4-1 victory over Espanyol in the Spanish Cup last month.
Turan did not start and missed last weeks cup game against Valencia nursing a foot injury but he was brought on in the last 15 minutes.
Luis Suarez scored a hat-trick including one of the most audacious penalties ever seen. Lionel Messi did not shoot the penalty but instead passed it to the Uruguayan international who found the back of the net.
Messi, Rakitic and Neymar scored the other goals on the night in the victory that saw Barcelona move three points clear of second placed Atletico Madrid.
