Barcelona maintained their flawless start to the La Liga season with an emphatic 5-0 victory over struggling Valencia at Mestalla.
Hansi Flick's side needed just five minutes to open the scoring.
Lamine Yamal raced behind the Valencia defence before calmly converting Fermin Lopez's perfectly weighted through ball.
Barcelona doubled their advantage through Lopez, who fired Anthony Gordon's lay-off into the bottom corner beyond Stole Dimitrievski.
It was Lopez's fourth goal of the campaign, while Gordon registered his fourth assist in as many matches.
The visitors showed no signs of slowing down after the break, with Raphinha adding a third.
Lopez was once again at the heart of the move, carrying the ball forward before setting up the former Leeds United winger for a simple finish.
It was Raphinha's sixth goal of the season and his 50th in La Liga.
Pedri then made it 4-0 following an excellent one-two with Dani Olmo, calmly slotting the ball beyond Dimitrievski to underline Barcelona's dominance.
Yamal completed the rout after more impressive work from Olmo.
The midfielder weaved his way through the Valencia midfield before releasing the youngster, who finished confidently for his second goal of the afternoon and fourth of the season.
The comfortable victory also provided Flick with an opportunity to introduce former Premier League players Harvey Elliott and Gabriel Jesus, who both made their Barcelona debuts from the bench.
Rodri, meanwhile, made his first start for the Catalan giants following his £65m summer move from Manchester City.
Barcelona took full advantage of Real Madrid's surprise defeat by Real Betis on Friday and now sit three points clear at the top of La Liga.
Flick's side have won all four of their league matches, scoring 17 goals and conceding only twice.
The situation is considerably different for Valencia, who remain bottom of the table with just one point and one goal from their opening four matches.
Frustration among the Valencia supporters was evident before the game, with a section of fans staging a protest by delaying their entrance into Mestalla until the 19th minute – a reference to 1919, the year the club was founded.
Barcelona will now turn their attention to the Champions League as they prepare to host Feyenoord on Wednesday.
Valencia, meanwhile, travel to Sevilla on Friday as they continue searching for their first victory of the season.
