Mane left the Reds for Bayern Munich last week.
Bacary Cisse, who acts as an adviser to the Senegal captain, told After Foot on RMC: "Yes, PSG did indeed 'attack' Sadio. Afterwards, you know not to make too much noise in these circumstances because there are negotiations.
"Leonardo had several contacts with his German agent, they saw each other, they discussed the ins and outs of a possible transfer from Sadio to PSG, but it ended there. Everyone knows that Leonardo was on an ejection seat, we had to wait."
He also said: "Sadio is an OM supporter. Tomorrow, he is wearing the Bayern Munich jersey and you ask him what his favourite team is, he will tell you Olympique de Marseille. One day in Marseilles? It will depend on what the Marseillais will offer, it may depend on Sadio."
