The Ronald Koeman era at Barcelona got off to the perfect start as Ansu Fati scored after only 15 minutes thanks to some great work from Jordi Alba.
But the youngster wasn’t done there, and doubled his account for the evening just moments later with a clinical finish.
Lionel Messi was soon getting in on the act, scoring his first of the campaign from the penalty spot.
And then right before half-time a Pau Torres own goal essentially put the game beyond Villarreal’s reach.
After the break the Catalan side took their feet off the gas but it didn’t matter as they ran out comfortable winners on Koeman’s debut match.
