The first was the departure of Unai Emery in the summer and the second a warning to the player from the club's ultras.
"His vast passion for football and his exceptional work ethic saw the club cement its place amongst the football elite, both in France and internationally", PSG president Nasser Al-Khelaifi said in a note on the club website.
Emery, as translated by Jonathan Johnson of ESPN FC, broke the news during Friday's meeting with the media: "I have told the players, (sporting director) Antero (Henrique) & the president (chairman & CEO Nasser Al-Khelaifi) that it is finished". In the French club, former coach of "Seville" worked with 2016.
Emery, who won the Europa League three years running with Sevilla, has previously been linked with a move to Real Sociedad.
Chelsea manager Antonio Conte has insisted he has not been asked by PSG to take over from Unai Emery when he leaves the Ligue 1 side in the summer. Last season, the loss to Barcelona was a huge shock for the club and this season it was Real Madrid that ruined the party for Neymar and co.
Wenger, 68, is leaving Arsenal at the end of the season after 22 years in charge of the club but would like to continue working at the highest level.
"To achieve its number one objective, which is the Champions League, the club first of all needs to be strong in France", said Emery, 46.
"I'm going to see what's best for my future", Emery said.
