But when asked about PSG's star-studded "MCN" attack - Mbappe, Edinson Cavani and Neymar - Robben was unfazed: "The important thing is the performance of the team, not just to focus on particular players". When the Brazil star joined from Barcelona in a world record 222 million euro transfer, Bayern CEO Karl-Heinz Rummenigge said the German side would never spend so much on a player, and called for the introduction of a player's salary cap.
Dani Alves, one of Neymar's compatriots and one of his few allies at the club, is said to have organised a team-bonding session to close the rift but that it ended being "as animated as a funeral wake".
Qatari Nasser Al-Khelaifi, head of the Paris Saint-Germain FC club, tried to resolve the outstanding dispute between Neymar and Cavani by offering one million euros to the latter in return for giving up the free kick.
In the second half, the Ligue 1 giants were awarded a penalty and both players wanted to take the spot-kick, but it was Cavani who eventually took the shot and missed.

And if he can keep Neymar quiet, he'll underline why Germany boss Joachim Low is such a big fan, saying: "Joshua is one of the biggest talents I have seen over the past 10 years or so".
With Everton looking for a forward to replace Romelu Lukaku, Cavani could present an appealing option for Ronald Koeman's side. Today, in sporting terms, we have more enemies.
The game will be a special occasion for Bayern coach Carlo Ancelotti, who is back at the Parc des Princes for the first time since leaving PSG in 2013 after leading them to the Ligue 1 title.
Bayern's front line is also tasty though, and expect most of the goal threat to come from Robert Lewandowski who has seven league goals so far this season - none of his team-mates have more than two. He gave the club added experience.
