Lionel Messi made his home debut for Paris St-Germain but was substituted off in the second half when they beat Lyon and won six of six wins.
Summer newcomer Messi hit the post and crossbar with a free kick in the first half, forcing Anthony Lopes to save, but was below his best.
When the score was 1: 1, the 34-year-old was replaced by right-back Achraf Hakimi and did not look happy about the end.
Messi received applause but no standing ovations from his fans.
The striker, who left Barcelona this summer, didn’t stop but said something briefly to coach Mauricio Pochettino as he walked past him onto the bench.
Another PSG substitute, Mauro Icardi, scored the winning goal in added time in the Ligue 1 match when he headed a Kylian Mbappe cross.
Lucas Paqueta pocketed Karl Toko Ekambi’s cross and gave Lyon the lead.
But Neymar equalized with a controversial penalty. He appeared to be pulling Malo Gusto back in the penalty area, but the youthful Lyon defender was given a penalty instead.
Neymar waited for Lopes to move before sliding in.
“I asked how he was doing, he said he was okay”
PSG manager Pochettino said his decision to replace Messi was not controversial.
“I think we all know we have great players in this 35-man squad,” said the former Tottenham coach. “Only 11 can play, we can no longer play. The decisions in the game are made for the good of the team and each player.
“Every coach thinks about it. Sometimes it works, sometimes it doesn’t. Sometimes the players like it and sometimes they don’t. That’s why we’re here at the end of the day.”
“Those are decisions the coach has to make. As for his reaction, I asked him how he was doing, he said he was okay. That was it. That was our exchange.”
This was Messi’s third game for Paris St-Germain – the third game he has played for a club other than Barcelona.
For fitness reasons and because of the last international break, 40 days passed between his entry and his home debut.
He made his debut last month as a substitute in the second half in a 2-0 win over Reims, with the goals scored before his introduction.
He made his first start on Wednesday in a 1-1 draw in the Champions League against Club Bruges. As in that game, Mbappe, Neymar and Messi’s much hyped top three started on Sunday.
Messi hit the corner of the woodwork in Belgium and again in Paris – and is still waiting for a first goal in PSG colors.
He showed some moments of playing alongside his old Barcelona teammate Neymar, but there is still work to be done to blend in with the rest of the team.
PSG’s next game is Wednesday’s Ligue 1 trip to Metz, which is about getting seven wins out of seven at the top of the league.
