Ousmane Dembele’s early goal and Lionel Messi’s late penalty saw Barcelona overcome Juventus 2-0 in the Champions League in Turin.
The Italian champions suffered their first defeat under new manager Andrea Pirlo but could still take encouragement from their performance in the absence of talisman Cristiano Ronaldo, with Alvaro Morata having three goals ruled out.
Ronaldo’s absence, confirmed by another positive Covid-19 test on Tuesday, drained a little of the fixture’s star quality to deny another head-to-head with Messi, but Barcelona did not care.
Dembele’s strike may have had a touch of fortune about it, but it came courtesy of a delightful Messi assist and was backed up by an assured and dominant display by the Spanish club.
The other game in Group G saw Ferencvaros come from two goals down to draw 2-2 with Dynamo Kiev as Franck Boli equalised in the final minute.
After their defeat to Manchester United last week, PSG got off the mark in Turkey with a 2-0 win against Istanbul Basaksehir thanks to Moise Kean's second-half double, although Neymar went off injured.
The other game in Chelsea's Group E saw Europa League champions Sevilla win 1-0 at home against Rennes thanks to Luuk De Jong's strike early in the second half.
Jadon Sancho scored from the penalty spot and Erling Haaland was on target in injury time as Borussia Dortmund gained their first points in Group F with a 2-0 victory over Zenit St Petersburg, who have now lost both of their matches.
Club Brugge and Lazio are both on four points, one ahead of Dortmund, after sharing a 1-1 draw. Hans Vanaken's spot-kick cancelled out Joaquin Correa's opener for the visitors.
