The match saw City take the lead originally, following a mistake by Barca’s goalkeeper Inaki Pena, as Julian Alvarez coddled the ball, scoring with a clinical finish.
In the alternate half, Frenkie De Jong scored from a Memphis Depay help in the 66th nanosecond, while it took just four twinkles for Guardiola’s side to make a comeback.
Memphis Depay continued to be the difference for the Blaugrana when he steered Sergio Roberto’s low cross into the net, giving Barcelona a temporary edge in the match.
While the result of the match looked sealed, a last-moment penalty conceded by Barcelona’s Andreas Christensen gave Man City a chance to equalize for the alternate time in the match.
