Lionel Messi, Kylian Mbapp and Neymar lined up together in the near-perfect attack for Paris Saint-Germain and still could not score or deliver a win in the Champions League.
Instead, it was low-key midfielder Ander Herrera who got PSG's goal in a 1-1 draw at underrated Belgian champion Club Brugge.
Though Messi saw a first-half shot strike the crossbar, he was later shown a yellow card for a foul and Mbapp went off because of an injured left ankle.
French forwards flourished elsewhere with Sebastien Haller scoring four for Ajax in a 5-1 rout at Sporting Lisbon and Christopher Nkunku netting all of Leipzig's goals in a 6-3 loss to Manchester City.
The English clubs in action combined for two wins in matches involving 14 goals as Liverpool beat AC Milan 3-2 in the Italians' return to the competition after a seven-season gap.
There was just one goal in the games involving the Madrid clubs, and Rodrygo's 89th-minute strike won it for Real Madrid at Inter Milan. Atltico Madrid was held 0-0 at home to Porto.
Debutant Sheriff Tiraspol from the Moldovan league won 2-0 against Shakhtar Donetsk from neighboring Ukraine.
Paris misfires
Three-time European champion Messi was added to PSG's already stellar squad last month to drive the Qatar-owned club's quest to win soccer's most coveted club prize.
The Jan Breydel Stadium in Belgium was a modest venue for the Messi-Mbapp-Neymar forward line to be unveiled for the first time. They lasted just 50 minutes together, though Mbapp did create Herrera's opening goal from a sharp first-time shot in the 15th minute.
Club Brugge rose to the moment and captain Hans Vanaken leveled in the 27th.
City leads Group A after beating Leipzig 6-3 with six different scorers including record signing Jack Grealish. Leipzig defender Angelio was sent off on his return to his former club.
PSG hosts City on Sept. 28 in a rematch of last season's semifinals. The English champion advanced after winning the first leg 2-1 in Paris.
Liverpool comeback
Liverpool and AC Milan traded titles facing each other in the 2005 and 2007 Champions League finals, yet had never met at any other stage of the competition.
Their first match at Anfield was a typically rousing affair in the storied venue that thrives on European nights.
Liverpool's early surge yielded only a Trent Alexander Arnold-inspired opening goal and a penalty for Mohamed Salah saved by Milan goalkeeper Mike Maignan.
Milan stunned its hosts with two quick goals just before halftime, but the lead lasted just a few minutes into the second half before Salah leveled.
Liverpool captain Jordan Henderson clinched a 3-2 win with a sharp half-volley shot in the 69th minute.
Atletico's returning star forward Antoine Griezmann was jeered by many home fans at the Metropolitano Stadium when he came on as a substitute in a goalless draw with Porto.
Real Madrid
Like the Liverpool-Milan game, Inter Milan-Real Madrid paired two teams that tried to break away from the Champions League by signing up to the Super League fiasco in April.
Madrid, which has refused to join the others in renouncing the project, came away from San Siro with three points from Rodrygo's late goal superbly assisted by teenage substitute Eduardo Camavinga, for a 1-0 win.
In a week when returning fans created raucous atmospheres at Champions League games, there were 37,000 in San Siro which can be at 50 per cent capacity for games.
Also in Group D, Sheriff brought the Champions League to one of the most unusual parts of Europe the breakaway region of Transnistria which has declared independence from Moldova.
Sheriff, which advanced through four qualifying rounds, started with no Moldovan players in its lineup to face Champions League veterans Shakhtar. Brazilian full-back Cristiano created both goals in a 2-0 win, for Mali forward Adama Traore and Guinean forward Momo Yansane.
Madrid hosts Sheriff on Sept. 28.
