Ally McCoist has paid tribute to Walter Smith following the news of the former Rangers manager's death at the age of 73. 

Smith and McCoist worked together at Rangers between 2007 and 2011 as manager and assistant manager, before McCoist took the reigns following Smith's retirement. 

Describing Smith as a "second father", pundit McCoist said he was "devastated" to learn of the death of one of his "best friends". 

"He means everything to a lot of folk. He was my boss, my coach, my second father and then turned into one of my best friends." McCoist told TalkSport.

"The loss is absolutely incredible.

"The good thing is he’s not in pain. I went to see Walter recently, I spoke to him at the weekend and we knew that it would be a matter of time. But it still does not take away the pain and the grief.

"I could sit here and tell you about Walter Smith until the cows come home, but what I will say he was the best husband, father, friend, everything you want from a man.

"I can’t tell you how devastated I am."

What has Rangers said about the death of Walter Smith? 

Rangers chairman, Douglas Park said in a statement: "On behalf of the Rangers board of directors, staff and players, I convey my deep condolences to the Smith family.

"Walter leaves behind a wife, children and grandchildren, all of whom are in our thoughts and prayers at this difficult time.

"It is almost impossible to encapsulate what Walter meant to every one of us at Rangers. He embodied everything that a Ranger should be.

"His character and leadership was second to none, and will live long in the memory of everyone he worked with during his two terms as first team manager.

"I spoke with Walter as recently as last weekend. Even when he was battling illness, he was still able to provide advice and support.

"For that, I am personally grateful. I know that he continued also to maintain dialogue with senior members of staff, including our manager, Steven Gerrard.

"Walter will be sorely missed by all of us at Rangers.

"Winning 10 top-flight titles as manager, five Scottish Cups and six League Cups, as well as leading his club to the UEFA Cup Final in 2008, he will be remembered by the football community across the world.

"His spells as Scotland manager as well as managing in the English Premier League underlined his credentials as one of the great modern day football managers.

"However, for Rangers supporters, he was much more than just a football manager. Walter was a friend to many, a leader, an ambassador and most of all-a legend."
