Former France midfielder, Emmanuel Petit has claimed Paris Saint-Germain are “not a football club” and said the whistles being aimed at Lionel Messi have become an “insult to football”.
Messi was booed by his supporters during a Ligue 1 clash against Lyon last weekend.
Petit has insisted that the 35-year-old should be shown greater respect.
The 1998 World Cup winner told RMC Sport: “When I hear that, for me, it’s an insult to football.”
Petit has also encouraged Messi to leave Parc des Princes, as no footballer improves at the French club.
He added: “It’s not a football club. It’s a pre-retirement club, even for 20-year-old players.
“Nobody has improved while at PSG, is that Messi’s fault? He’s the magician with a wand, it’s up to the players around him to make an effort.
