There is also increased anxiety amongst the PSG squad of the increased influence of the growing Brazilian cohort within the dressing room who are increasingly seeking to take control of the decision-making process.
Unless you've been under a rock for a few days, you'll nearly certainly know all about the very public disagreement Neymar and Edinson Cavani had over the weekend.
Shortly after the players went through an adaptation period it was quite clear who the "king" was.
The PSG owner faces a tough decision as he looks to smooth things over and attempt to mend the broken relationship between his two first-team stars.
Having already scored three times from the spot this season, Cavani assumed the responsibility would once again be his.
The Spaniard wants Cavani and Neymar to share penalties and that could be the only way to settle a spat that Neymar never experienced at the Camp Nou. However, things seem to have heated up between Cavani and Neymar and the French club will be anxious at this public breaking down of relationships.
Cavani has been one of PSG's most important players over the last four years, scoring 139 goals in 206 appearances.
PSG broke the world transfer record to lure Neymar away from Barcelona over the summer, with a €222 million deal taking him to the French capital.
But Sunday's match was less encouraging, with none of them on the scoresheet. Then when the penalty opportunity came up, Cavani won the argument and took the spot kick, but it rattled against the bar.
June 2015: At the Copa America, Neymar seems to have deliberately hit Colombian forward Victor Ibarbo with the ball following Brazil's 0-1 defeat to Colombia. Man Utd also failed to secure his signing.
PSG have not slipped up yet, but Sunday's game showed that Emery has plenty on his plate.
