Neymar argued with Cavani over who was going to take a spot-kick and when they got a free kick at the edge of the box.
They might not be Neymar and Kylian Mbappe, but Cavani would be able to call upon the creative services of Gylfi Sigurdsson, Wayne Rooney and Davy Lkaassen, were he to move to Merseyside. If anything, this fire is raging more than ever.
In that regard the evening was a resounding success for Unai Emery's team, although the German club were some way short of their usual standards.
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". PSG have since denied this. No Neymar, no win. Rightly or wrongly, the latter's consummate professionalism will either continue to grate with his new teammate or see him relinquish his role as penalty king because he always puts the collective before the individual.
The Uruguayan won that battle of wills but failed to score and Emery has since assured he has spoken to both players regarding the issue.
Naga terrorists killed in army ops along India-Myanmar border
The army said one of its columns operating along the border was sacked upon by "unidentified insurgents" at about 4:45 am. The Army however denied that the Indo-Myanmar border was crossed and claimed it was not a surgical strike.
Neymar was allowed to cut in from the left before picking out Alves, who arrived unmarked in the area to take a touch and finish past Sven Ulreich, standing in for the injured Manuel Neuer in the Bayern goal.
El Pais says there is a general feeling of resentment towards Neymar - who is on double Cavani's wages - because so numerous players left at the club feel they were effectively put up for sale over summer so PSG could afford its €222m deal for the Brazilian. The France international's decent but far from dazzling start to life back home in the French capital already suggests this might be required sooner rather than later.
Argentine winger Angel Di Maria also returns to the PSG squad after almost three weeks out injured.
Nevertheless, the biggest test for Bayern's shaky defence - which threw away a two-goal lead at home to struggling Wolfsburg in a 2-2 draw last Friday - will be to contain the "MCN" trio. That might be a problem for them as the Champions League adds fatigue to these players. "I have a lot of respect for them, their team is a lot better and their forward line has nothing to envy from Bayern, Real Madrid or Barcelona, they are at the same level".
