Keane has criticised his team mates for swapping their hunger to win trophies for Rolex watches and fast cars but Ferdiunand is still a fan:
"Roy's brilliant. He's got the desire to win which is why he's captain of United. His desire shows on the pitch. You can really look up to him."
Gary Neville, meanwhile, feels that the public should read the entire book before forming an opinion.
"I know Roy is in the headlines because of his autobiography, but I will not comment on the rest of the contents until I have read it, which I plan to do at the earliest opportunity because I like the guy, share a dressing-room with him and would be interested to read about his past," Neville said in the Times.
"I would prefer to read the whole book rather than rely purely on the serialisation because I know from experience how certain chapters can be distorted in short form."
Not surprisingly Keane has shrugged off the furore surrounding his book:
"It wasn't hard to concentrate - not one bit. I try to tell the truth and that's what I've done."
