Luis Suarez made his Barcelona debut off the bench as the Spanish giant hammered Mexican outfit Club Leon 6-0 at Camp Nou.
Suarez replaced Rafinha to a rousing reception with 13 minutes remaining, but understandably looked a little rusty on his first appearance since the 2014 FIFA World Cup.
The Uruguay international arrived from Liverpool for a reported fee of $142.5 million last month under something of a cloud having been banned from all football activity for four months after biting Italy defender Giorgio Chiellini during their World Cup Group D match in Brazil.
However, the Court of Arbitration for Sport last week cleared him to train and play in non-competitive matches, something coach Luis Enrique took full advantage of in fielding Suarez as a late substitute in an easy Trofeo Joan Gamper win.
Barcelona was already leading 4-0 thanks to goals from Lionel Messi, Munir El Haddadi and a double from Neymar before Munir and Sandro rounded off the scoring.
"Today was an unforgettable day," Suarez tweeted with a photograph of himself and new team-mate Andres Iniesta after the match.
"Thank you all for your affection."
Barcelona sporting director Andoni Zubizaretta said the club will give the 27-year-old former Liverpool striker time to get used to his new surroundings.
"We will give him the time so that he can see he is integrating into the team and he will adapt to the team in training," he told Barca TV.
"He will get to know our style of play and with his quality he will help us. His teammates will get to know him and the idea is that when he returns, he does so at 100 per cent."
Midfielder Iniesta believes last season's Premier League Player of the Year will not have any difficulty adapting to life alongside Messi and Neymar in attack.
"It is never easy when you come from another club, but, as I have said before, I think he will find a very healthy dressing room and I think he will adapt fine, because his talent is above everything else," he said.
Luis Enrique, the new Barca boss, was himself afforded a generous welcome from the Camp Nou faithful before kick-off, and could also welcome Lionel Messi and Neymar back after their exertions at the FIFA World Cup.
The home side got off to an ideal start when Messi and Neymar both found the target in the opening 12 minutes, before the star pairing linked up again shortly before the break, allowing the Brazil international, showing few ill-effects of the back injury that cut his FIFA World Cup short, to score his second with a nonchalant backheel.
Munir El Haddadi tucked home a fourth early in the second half before Suarez, who can not play in Barca colours again until late October with his competitive debut potentially coming against Real Madrid, was brought on.
Youngsters Munir and Sandro then wrapped up a comfortable Barca victory in its final match before beginning its La Liga campaign against Elche this weekend.
