Star forwards Neymar and Edinson Cavani argued over who should take a penalty kick as Paris Saint-Germain extended its perfect record in the French league to six matches with a hard-fought 2-0 win over lyon on Sunday.
Facing its stiffest challenge this season against the seven-time champions, PSG needed two own-goals from lyon defenders Marcelo and Jeremy Morel.
PSG now leads defending champion Monaco by three points.
PSG enjoyed most of the possession but its attacking "MCN" trident of Kylian Mbappe, Cavani and Neymar was not as flamboyant as in previous matches. lyon defended well and prevented Neymar from making his mark while Cavani had only a few touches.
lyon goalkeeper Anthony lopes made several decisive saves and sent a penalty kick from Cavani onto the bar in the 79th minute. Moments before, Cavani and Neymar had been seen arguing about who should take the penalty.
A few minutes before that, Cavani had tried to take a free kick but Neymar's good friend and fellow Brazilian Dani Alves took the ball and gave it to the former Barcelona star.
Cavani thrived last season as PSG's main striker, finishing as the French league's top scorer and bagging a remarkable 49 goals in 50 games across all competitions. Neymar's arrival from Barcelona for a world record 222 million euros ($262 million) has taken the spotlight away from him.
Cavani went back to the dressing room straight after the final whistle while his teammates celebrated on the pitch
PSG was fortunate to open the scoring 15 minutes from time when Marcelo deflected a flick from Cavani into his own net.
The hosts doubled their lead nine minutes later when Mbappe was set up by Neymar and forced lopes into another good save, with the ball bouncing back onto Morel and into the net.
dybala shines with hat-trick in Serie A
Milan: Paulo Dybala has repeatedly said he doesn't want to be likened to his more famous compatriot lionel Messi but the comparisons will keep coming as the Argentina youngster goes from strength to strength.
Dybala marked his 100th Juventus appearance with his second hat trick of the season to help the Bianconeri win 3-1 at Sassuolo on Sunday and stay perfect in Serie A.
Napoli, which crushed Serie A debutant Benevento 6-0, has also won its opening four fixtures as has Inter Milan, which beat Crotone 2-0 on Saturday.
"Stop comparing me to Messi, I'm Paulo Dybala," he said.
"Every player is himself. I'm Dybala. It's not that I don't like the comparisons with Messi, but Messi is a player who has won five Ballons d'Or.
"The comparisons don't seem absurd to me but I want to be myself. I don't want to be compared to any other player. I want to have my career, win my trophies, score my goals and play my way."
Dybala now has eight goals in Juve's opening four league matches, just three fewer than he scored in the whole of last campaign.
All three of his goals Sunday were impressive.
Dybala netted his 50th goal for Juventus in the 16th minute with a first-time shot into the top right corner from 25 yards after Mario Mandzukic rolled the ball across from the left.
