The Rangers manager paid tribute to a “fantastic guy” immediately upon hearing about the former Scotland international’s death at his club’s Tuesday morning press conference.
He said: "That's a shock and a surprise to me. I didn't know that. I'm really disappointed to hear that. He's an iconic figure at Liverpool Football Club.
"He's someone I've met on numerous occasions. A fantastic guy. Really insightful in terms of his career and experience at Liverpool and trying to pass on a lot of knowledge and expertise.
"So I'm really devastated to hear that news to be honest with you. Shocked as well, so I'd like to pass on my condolences to all his family and everyone close to the Saint. He's a legend and an iconic figure at the club and someone I've got incredible respect for."
