Monaco swiftly took the lead before 17-year-old Lamine Yamal, in front of NBA legend Michael Jordan, who watched on from the stands, brought 10-man Barca level and became the second-youngest goalscorer in the Champions League.

MONACO (AP) — Barcelona’s perfect start to the season ended with a 2-1 loss at Monaco in the revamped Champions League on Thursday, a defeat which happened after defender Eric Garcia was sent off after 11 minutes.

Barcelona had a dreadful start at the Stade Louis II stadium when Garcia was shown a straight red card 11 minutes in for a foul on Monaco's Takumi Minamino, who was clear in front of goal after a misplaced pass from goalkeeper Marc-Andre ter Stegen.
