Barcelona thrashed Valencia with Marcus Rashford involved in a La Liga goal for the first time.
Fermin Lopez, Raphinha and Robert Lewandowski scored two goals each for the Spanish champions.
Half-time substitute Raphinha’s first goal – to make it 2-0 – came from a brilliant left-wing cross from England forward Rashford.
The Manchester United loanee, making his second start for Barca, played 67 minutes and had two efforts off target in a lively outing.
Lopez had run onto Ferran Torres’ ball to net their opener and smashed in a fantastic strike from outside the box to make it 3-0. Raphinha then rifled in their fourth.
Lewandowski, also a substitute, finished off Dani Olmo’s pass and then dinked in a sixth – a goal given by the video assistant referee after initially being ruled offside.
Barca could easily have won by more goals, with Torres also hitting the post after a Rashford cross was flicked into his path.
The game was played at the 6,000-capacity Johan Cruyff Stadium, where Barca’s B team usually play, because the Nou Camp is not ready yet after being redeveloped.
