Mbappé watched from the bench as PSG went a goal down at En Avant Guingamp, and then saw the reigning French champions get the benefit of a favourable VAR decision that denied the hosts a second.

His break after helping his country claim football's ultimate prize in Moscow on 15 July ended after the half-time interval, and 45 minutes, two world-class goals and a stunning individual performance later, Mbappé was back with no thought of resting on the laurels he earned in Russia.

"We won, we celebrated, but football continues, my career is starting, I have very high ambitions whether that be with PSG, France or individually. You don't have the time to hang around doing nothing," the 19-year-old, who replaced Timothy Weah at the break, explained.

"I contributed something, but it's the whole team that wanted to do something different. We started timidly. I helped the team with two goals, but there wouldn't have been a problem even if I hadn't come on."

While Mbappé ensured PSG picked up a second successive win to start a top-flight season for the fourth consecutive year, it was Neymar Jr's 53rd-minute penalty that had brought his team back on level terms.

Mbappé insisted the Brazilian, who had made his Ligue 1 Conforama debut at the Stade du Roudourou almost to the day a year before, remains the club's biggest name.

"There are a lot of stars. Neymar is a superstar, more than me. He worked a lot at Barcelona for that," said the former AS Monaco prodigy. "With a goal and an assist, he didn't do too badly either. I tried to contribute what I can and help the team win."
