"I think it's their job if they go on television, it's their job to say something. Sometimes they say the truth, probably, sometimes they criticise the younger players which isn't good, in my opinion," Serbia international Matic told Omnisport.
"Especially if you're an ex-player of Manchester United and you criticise the players and you know you've been there 10, 15, 20 years ago, it's not good.
"You have to help the players if you can. But they probably get money to work there and they have to say something."
