Hansen wrote in the Telegraph: "Although he won the Premier League as Blackburn manager in 1995 and also managed Newcastle and Celtic, he only ever really wanted to be at Liverpool and he waited so long to go back there.
"Even when he was at Liverpool in his role as ambassador, prior to replacing Roy Hodgson as manager last year, he would pour his heart and soul into the club and spend more time there than anybody else.
"Whenever I would call him on a Sunday, I would ask him where he was and he would be down at the Academy. He was non-stop.
"So as his friend, I am really upset for Kenny because I know just what it meant for him to be back at Anfield.
"He will be torn apart by the way it has ended and the reality that he will no longer be able to go back and mix with the players."
