Brazil's talisman Neymar has been in the spotlight this week after an emotional press conference on Friday, during which he broke down in tears and walked out after becoming upset by the line of questioning.
Neymar has experienced mixed fortunes at the Parc des Princes since joining Emery's side from Barcelona for a world-record £198million fee this summer.
He said: 'He [Neymar] is a great player who, due to his circumstances or feelings or thoughts, made a decision to leave.More news: Gal Gadot won't do Wonder Woman sequel if Brett Ratner is involved
"He facilitated my integration, took me under his wing", he told the club's official website. I'm a player who wants to give everything on the pitch.
The young Frenchman, who himself joined PSG in the summer, also insisted Neymar had a big influence in helping him settle into his new team.
Real Madrid came close to signing Neymar from Santos prior to his move to Barcelona back in 2013 and the player has always been seen as "the one that got away" by Perez.
"Mbappe said: "[Cavani is] superb. I know what it feels like, and I want to experience that thrill again with PSG. He is very available, very mobile, and has an extraordinary finishing quality.
It's far more likely Neymar simply posed the question as a joke, given that without him, the club have established themselves eight points clear of Real Madrid in an electric start to La Liga this season. He is a good person and a very great professional.
