The 22-year-old has recently been strongly linked with a move to Arsenal.
The France international insists he is keen on leaving PSG if the club signs a new defender this summer.
“If another defender comes in, I will do everything to leave because I have to think about my future,” he told L’Equipe.
“My objective this season is to be in the starting 11 at a club. So I am opened to propositions of clubs keen to play me and allow me to go on improving.
“I am not keen to experience the last six months of last season. I preferred not to talk about my personal case to not disturb the group.
“However, I had hopes to be called for Euros. But when I saw the list I had tears in my eyes. It was two years of work that fell through as I have always been called since August 2010.
“So I need to play at my club – that is very clear. That is why I am opened to propositions and I am thinking about a departure.
“It is the very first time I say that. So far at Paris I have always had trust and I tried to justify it. But now I don’t feel that trust from the coach.
“When you are player and you hear a player in your position is being searched for, of course you feel unwanted and pushed to the exit door.
“I had a talk with Ancelotti just before holidays. His words didn’t reassure me.
“I already had talks with coaches that relied on me, but it is the very first time I left the office with such feeling. He just told me to accept competition.”
