Tiger Woods thinks former swing coach Hank Haney is unprofessional for writing a book about their time together.

Haney's book, The Big Miss, details his six-year tenure as Woods' swing coach before their mutual parting in May 2010. Although Haney has praised Woods as the greatest golfer who ever lived in an interview with The Associated Press earlier this month, Woods isn't happy about the book.

I think it's unprofessional and very disappointing, Woods told ESPN.com, especially because it's someone I worked with and trusted as a friend. There have been other one-sided books about me, and I think people understand that this book is about money. I'm not going to waste my time reading it.

Haney helped guide Woods to six majors and 31 PGA Tour wins, but was also present for when his career hit rock bottom when his extramarital affairs became public. Since the affairs became worldwide news in 2009, Woods has struggled mightily on the golf course. He has only won once since breaking up with Haney in 2010 -- a win at the Chevron World Challenge in December -- and has battled a multitude of injuries that have derailed his once superb golf game.

In public interviews about the book, Haney has said that his focus was documenting Woods' golfing greatness and not the extramarital stuff.

I was a witness to greatness, Haney told The Associated Press on Thursday. And I get asked the question all the time about Tiger. I wanted to talk about it and I wanted to share it with people. That's the bottom line. I'm not sure I understand the unprofessionalism part. He hasn't read the book. There's a lot of positives in there. I think he's the greatest golfer who ever lived.

I was just in a position to observe greatness and anyone who observes greatness likes to share it. I feel like I wrote a book that was fair and honest. It's golf history.

Haney is considered to be one of the greatest golf coaches in the game and has also worked with two-time major winner Mark O'Meara. Woods claims that Haney never tried to contact him about the book, but did make sure to tell ESPN he was thankful for everything he did for me.

Woods is currently preparing to pair up with Dallas Cowboys quarterback Tony Romo for the AT&T Pebble Beach National Pro-Am.
