Thomas Meunier has refused to give Paris Saint-Germain team-mate Neymar grief despite the Brazilian trying to force his way out of the club in the summer.
Neymar reported late to training on Tuesday but head coach Thomas Tuchel confirmed this was authorised as the forward had a "personal thing".

Meunier, though, feels supporters need to move on from that saga and give Neymar their backing.
"Whistling is not the answer, I'm happy about what he brings," Meunier told a press conference.
