The comfortable win saw PSG go second in Group H, ahead of RB Leipzig on goal difference, but the positive result - clinched by a double from Italy international Moise Kean (64', 79') - was partly overshadowed by Neymar's being forced off injured mid-way through the first half (26').

Tuchel: 'We have to wait'

"It was necessary fore him to come off," said Tuchel of his star man, who has been in strong form early in the season. "It's the adductor. I hope it's not a serious injury, but we have to wait for the imaging tomorrow. It wasn't severe pain, but he felt uncomfortable. In a very tight schedule like this, it can cost him a few games. But I'm not sure at the moment."

Further tests will be carried out on Thursday, but there is no question that it's unfortunate timing for the capital club, who face Nantes, RB Leipzig and Rennes in the next nine days.

Kean as mustard

However, centre-forward Kean's scoring form will be something of a consolation for the Parisians, who have been battling injuries and suspensions for most of the early part of the season. A late signing in the summer window, Kean took a moment to adjust to life in Paris but, after scoring his first two Ligue 1 Uber Eats goals in the 4-0 win over Dijon at the weekend, now has four in two outings.

"We needed to win the match this evening after the home defeat against Manchester United last week. Mission accomplished! I work hard and I continue to work hard to help the team. I am very happy, these two goals bring me confidence," said the 20-year-old, who signed on loan from Everton. "The first minutes of the game weren't easy this evening, but in what followed, we were able to find the chink in the defence's armour. It wasn't an easy match, we needed to stick together, to remain focused and patient."

PSG travel to Nantes for their Ligue 1 Uber Eats Round 9 clash at 21:00 CET on Saturday.
