Lionel Messi came on as a substitute to make his Paris Saint-Germain debut on Sunday but Kylian Mbappé stole the show by scoring both goals in a 2-0 win against Reims in Ligue 1.
Messi, wearing the number 30 jersey, came off the bench in the 66th minute to replace Neymar at the Stade Auguste-Delaune, where fans in the sell-out 21,000 crowd had earlier chanted his name as he emerged to warm up.
The Argentine had not played since arriving in Paris from Barcelona almost three weeks ago, his last appearance in any game dating back to the Copa América final on July 11, when he led his country to victory against Brazil.
The six-time Ballon d'Or winner will have to wait for his first goal with his new club, and his first start, which could come when PSG host Clermont in their next match on September 11.
"I'm very happy that he made his debut. It was very important for him," PSG coach Mauricio Pochettino told broadcaster Amazon Prime after Messi's low-key first appearance in a PSG shirt.
"He is still far away from his best form but he has been training well and he will be fit in the next two weeks, after the international break and, yes, we are waiting for the best from him."
The week leading up to this game had been dominated not by Messi but by talk of Mbappé's future, with Real Madrid reportedly having two offers for the France World Cup-winning striker rejected.
The latest of these offers was understood to be worth 180 million euros (US$212m), an astronomical amount for a player whose contract expires at the end of the season and who will be free to negotiate a deal with a new club in January without PSG being able to get a transfer fee.
That amount is also equal to what PSG paid Monaco in 2017 to sign Mbappé, who was clearly eager to go out on a high if this was to be his final appearance for the club.
'Kylian is our player'
With the transfer deadline looming on Tuesday, the 22-year-old did not appear remotely distracted by the talk of a move as he headed in a glorious Angel Di Maria cross in the 15th minute to put the away side in front.
Mbappé then scored his second of the night, and third of the season, just after the hour mark, finishing off an inviting low cross to the back post by Achraf Hakimi.
"Kylian is our player and you know that in football and in business there is always gossip and rumours," Pochettino said of Mbappé.
"I think our president and our sporting director were very clear and he is still here. I am really happy to have Kylian.
"He is one of the best, one of the most important players in the world today and for him to be with us is a gift."
Reims were once France's pre-eminent club, twice reaching the European Cup final in 1956 and 1959, but it is a long time since the footballing spotlight has been on the city, 150 kilometres north-east of Paris in the Champagne region, to such an extent.
The home side, whose coach Oscar Garcia played for Barcelona in the 1990s, had what they thought was an equalising goal by Zimbabwe's Marshall Munetsi early in the second half disallowed for offside.
They put up a good fight but the chances of any team in France stopping PSG – even if Mbappé departs – are slim.
Neymar started, making his first appearance of the season, while Di Maria also played in an all-star attack.
They are the only team in Ligue 1 with the maximum 12 points after four games and they lie two points clear of surprise package Angers, who beat Rennes 2-0.
Defending champions Lille recorded their first victory of the Ligue 1 campaign as Yusuf Yazici and Jonathan David scored in a 2-1 win over Montpellier.
Monaco bounced back from their elimination from the Champions League in the play-off round in midweek to win 2-1 at Troyes, Sofiane Diop's brace securing their first victory of the league season.
