Ferguson has spent the last 23-years in charge at Old Trafford.
“My health will dictate how long I stay in the job,” Ferguson told the Daily Mail.
“That’s the only important thing. It is what you have to value most and what you have to protect most because without it you cannot do justice to yourself, your family or whatever you do in life.”
