In an interview, the Chelsea manager said: “Everything, his talent, the time he put his talent at the service of Manchester United and football in general.
“The passion that he has put in to everything, and after that in private moments, obviously, a good friend, a good person, a fantastic sense of humour. I like him very, very much.
“Now and again I’ve had questions to put to him and the way he has answered to me was always magnificent and a great support.”
Jose Mourinho was tipped to replace Ferguson as manager of Manchester United while he was still in charge at Real Madrid. But the summer of change at Old Trafford saw David Moyes step into the role, while Mourinho landed back at former club Chelsea.
The Portuguese has guided his Chelsea team to top spot in the Premier League going into Christmas Day, with the Blues firm favourites to win the league title.
