He has always been a reluctant public speaker but on Saturday, as he watches Chelsea at home to Liverpool, he wants to say something about his former boss whose title-winning side are 15th in the table and under pressure. “For me he [Mourinho] will always be the No 1,” Duff says. “It’s time to stick with him. There is talk of getting rid and replacing him. I know in the past at Chelsea that if a manager has struggled he has been out the door but Mourinho can build a dynasty. I would love to see him there in 10 years’ time.”
