Joe Cole: "Geri was a great servant for Chelsea, very successful in that he helped to win silverware and he is a great fella.
"Duffa, what a Chelsea legend, and a fantastic player and a great guy also. It will be nice to see them both.
"Obviously it is not Keegan's team at Newcastle at the moment but he has good players there.
"I worked with him once and he is a good manager, I know some of his staff and they know their football. It doesn't surprise me he has turned it around."
