Luis Suarez's second-half brace ensured Barcelona came from behind to beat Inter Milan 2-1 in the Champions League.
Lautaro Martinez scored in the second minute and the Italian side had further chances to extend their lead at the Nou Camp.
But Barca responded after the interval and two brilliant finishes from Suarez, the second six minutes from time, condemned Inter to their first defeat of the season under Antonio Conte.
The win moved Barcelona level with Borussia Dortmund at the top of Group F, three points ahead of Slavia Prague and Inter.
Liverpool's group rivals Napoli were held to a goalless draw at Genk.
The Partenopei - who beat Liverpool 2-0 at home in their opening match - had started brightly in Belgium, but were not able to find a breakthrough as Genk recovered from their 6-2 trashing in Salzburg.
Borussia Dortmund won 2-0 at Slavia Prague, with two goals from full-back Acham Hakimi, to put the Germans top of Group F on goal difference.
Stanislav Tecl had squandered the chance to equalise in the second half when through on goal, only to shoot into the side netting before Hakimi sealed victory with another well-taken late effort.
Chelsea's group rivals Valencia were beaten 3-0 at home by Ajax, who have a 100 per cent start.
Hakim Ziyech's spectacular effort broke the deadlock on eight minutes.
Daniel Parejo then missed a chance to equalise when he sent a penalty over the bar in the 25th minute.
Quincy Promes added a second before half-time, with Donny Van De Beek scoring a third in the 67th minute for last season's semi-finalists.
In Group G, Zenit St Petersburg beat Lyon 3-1 at home to top the table.
Artem Dzyuba put the Russians ahead in the 22nd minute, with an own goal from Ruben Dias given following a VAR review and Sardar Azmoun's solo effort wrapping things up. Raul De Tomas scored a late consolation.
Memphis Depay was on target as Lyon won 2-0 at RB Leipzig, with Martin Terrier also scoring in the second half.
