Diouf, on the sidelines with a hamstring injury, told The Sun: "One day I will catch up with him and we're going to talk.
"If I see him face-to-face, he's going to know what I think about him.
"He said some things about what happened to the guy Mackie.
"But I was upset about what happened to him with the injury because I don't want that to happen to anyone. I've got a heart too, you know?
"And what his manager said was s***.
"How can I see someone suffer, someone hurt, and say something bad to him? No way."
