Newcastle United legend Alan Shearer is convinced Jose Mourinho sought to humiliate Nemanja Matic yesterday.
The champions are reeling after defeat to Southampton.
Shearer said: "His players are not listening to him. He put Matic on at half-time and took him off 25 minutes later.
"That is saying to the player and to the rest of the players 'I am the boss, you're not messing with me and if you don't give me something I am going to humiliate you in public'."
