ALS research:
All funds raised through ticket sales for the game go towards aiding ALS research through the Luzon Foundation.
More than 90,000 spectators were at Camp Nou, but the amount of cash has not yet been announced.
The game was arranged in aid of Unzue, a former Barcelona team-mate and friend of City boss Pep Guardiola, who was diagnosed with ALS.
He spoke to the players and coaches prior to the game and gave an honorary kick-off, as well as addressing stadium.
“Thanks to the two clubs for their sensitivity to our cause,” Unzue said. “Thanks to all of you who have bought a ticket to be here today.”
Cole Palmer:
The 20-year-old said he was not treating the game as a friendly and saw it as an opportunity to show what he could do.
He almost scored with a chance that he created for himself in the first half before rounding off a neat move with a well-timed run at the back post.
Palmer is highly-regarded and his performance will add more belief that he can cope with big occasions.
“When I go out there, I’ve got to take my opportunity – tonight wasn’t really a friendly for me, because I’ve got to prove myself,” he said.
“When I play, I have to score and have to assist so I’m glad I’ve done that.”
Barca’s sales pitchers:
The financial situation at Camp Nou continues to be a minefield with a busy end of transfer window still expected.
New signing Jules Kounde made a start, but has been unavailable for the first two games of La Liga as he has not yet been registered.
Barca will either sell or ask players to take wage cuts before they can buy or make any more manoeuvres in their squad.
So it may have been useful that all three goalscorers have been linked with other clubs, although it’s not clear whether any will leave.
Aubameyang, who got the first, is a Chelsea target, De Jong has been chased by Manchester United all summer and Depay has been linked with Juventus.
Bernardo Silva:
Speaking of transfers, if the City midfielder didn’t feel special before, he will have done after the post-match press conference.
Both coaches took the opportunity to praise the Portuguese star, who has has been linked with a move to the Catalan giants all summer.
“I love Bernardo as a player,” Xavi said. “He understands everything and has an amazing ability to make decisions.”
Asked about his future again, Guardiola said: “We want Bernardo Silva with us but I don’t want anyone to be unhappy here.”
City fans will be happiest when the transfer window shuts and his stay is confirmed once and for all.
