Former Chelsea boss Ruud Gullit says he can't forgive Gwyn Williams over his sacking at Stamford Bridge.
Gullit spent three years at Stamford Bridge, initially joining as a player before moving into the role of manager at the west London club.
Speaking to BBC Sport, Gullit said: "The day before I was sacked, I was playing golf with one of my coaches, Gwyn Williams, and a couple of the players, Franco [Zola] and Kevin Hitchcock. I was trying to contact [Brian] Laudrup during our round [to try and sign the Rangers midfielder] but I couldn't get hold of him, which was weird.
"It turns out Gwyn, who was one of my closest friends and who had helped me a lot, knew exactly what was going on and that they were going to fire me.
"He was just playing golf with me to keep me away, to make sure I didn't go to any of the places where Laudrup was.
"Being sacked was a horrible experience, and there was no reason to do what they did. They made out it was over my contract demands but that was rubbish because there had not been any negotiations. They were going to do it anyway.
"The worst thing was what Gwyn did to me, though - I couldn't understand doing that to someone when you spend every day with each other. He didn't even have to say anything specific, he could have just told me to watch out because something was going on.
"That was the worst thing anyone had ever done to me, in my career or in my life. That was the biggest disappointment, that someone could do that to me, and I can't forgive him for that, I really can't.
"Everything else, though, I have put behind me. Am I still angry about being sacked? No way. I swallowed that a long time ago and moved on. Am I glad I came to England? Yes, of course."
