Mackay is convinced he'll learn plenty from for Manchester United manager Ferguson.
He said: "I've not read it yet but I will. I'm pretty sure there will be things other managers can learn. He will go down as probably the best British manager of all-time in history and I don't think that is an over-statement.
"How can you not learn from someone like that in football with the amount he has done and the experiences he has had?
"There are little things that anyone can take. You can always take things from other people - good or bad.
"I'm not surprised (by the criticism) at all. I don't think he will be losing any sleep over it put it that way.
"He has had enough on his plate and to be fair so I haven't spoken to him recently. He said managers should have full control of the team which is obviously what the manager should have."
