Surgery it is for Neymar, then, but perhaps there's a reason Emery tried to quash rumours of an operation for his star player and said he could be available.
Speaking to his arrival in Rio de Janeiro from Paris, collected by the main French media, the doctor specified that the attacker will be off the grounds from two and a half to three months.
The Brazilian, who signed for PSG in a world-record move from Barcelona previous year, is now a serious injury doubt for the Champions League last-16 second leg against Real Madrid at the Parc des Princes on March 6.
Mardrid now hold a 3-1 lead on aggregate over the Parisians.
And if his absence extends to 12 weeks, Neymar would be ruled out of the remainder of the Ligue 1 season, while his participation in this term's Champions League would be over unless PSG reach the final in Kiev. Emery looked positive after the win although he will surely miss Neymar, his star man.
"There is a small chance for Neymar to be able to play against Real Madrid - we have to be patient".
According to AS, it was actually Neymar who told PSG he wants surgery, which completely went against their wishes for him to undergo "a more conservative course of treatment". He's sad, and that's understandable, but he will be back soon. We could not take the risk of delaying the operation.
Despite reports claiming Neymar could be out for two months, Al-Khelaifi is hopeful of him returning just in time for the Champions League quarter-finals scheduled for the first week of April, should PSG get past Real Madrid in March.
The Brazilian striker is the face of PSG, which paid a world-record transfer fee of 222 million euros ($270.8 million) to acquire Neymar from Spanish-league powerhouse FC Barcelona last summer.
Brazilians care little about the impact on the Paris club. Their attention is entirely trained on the World Cup, where they have ambitions of walking away with a sixth title. I think the Real match is the most important.
"Today, we saw that the team and the players who played were good".
