Sunderland boss Martin O'Neill is ready to face Norwich City.
Tonight's game will be the first time O'Neill has come up against his former Celtic captain Paul Lambert.
Canaries boss Lambert said: "I will still be calling him gaffer on the touchline and that's something that will never change. I never use his first name and I never will because I have far too much respect for him.
"Anyway, he would probably still fine me if I did.
"He is obviously one of the best managers I've ever had and I loved every minute of my time at Celtic with him."
