Ex-Anfield captain Steven Gerrard has called Ian St John, who has died at the age of 82, a 'Liverpool icon'.
St John was a key player in the great Liverpool team assembled in the 1960s by Bill Shankly which rose from the second division to win two English league titles and an FA Cup in 1965, in which he scored the winning goal in the final against Leeds United.
His death has been mourned throughout football and is especially sad for those with connections to Liverpool, for whom St John was pivotal in turning the club into the "bastion of British football" Shankly wanted it to be.
Gerrard was told the news during his Tuesday media conference as Rangers manager, and said: "He's an iconic figure at Liverpool Football Club. He's someone I'd met on numerous occasions and he's a fantastic guy.
"He was really insightful in terms of his career at Liverpool and his knowledge and expertise, and he always wanted to pass that on.
"I'm really devastated to hear the news, and I'm shocked. I'd like to send my condolences to his family. He's someone I've got incredible respect for."

The thoughts of everyone at Liverpool Football Club are with Ian's family and friends at this sad and difficult time.
Rest in peace, Ian St John 1938-2021.
Gerrard's words were echoed by another Liverpool legend, Sir Kenny Dalglish, who said: "I think it's right to use the word 'icon' and I send my prayers to Betsy, his wife, and the family and I just hope they are coping as well as they possibly can.
"He certainly was, and deservedly so, an iconic figure in and around Liverpool Football Club because he came in at the very beginning with Shanks and big Yeatsy (Ron Yeats).
"He got off to a 'terrible' start by scoring a hat-trick against Everton at Goodison in the Liverpool Senior Cup, so I think after he did that he was always going to be revered in and around Liverpool.
"It's because of what he did in those early days, Shanks especially, the Saint and Big Yatesey, his big mucker, and it's because of them where this football club is at this particular moment in time. We should be eternally grateful for what he did for the football club."
Jimmy Greaves, with whom St John formed a highly popular partnership for the TV show Saint and Greavsie from 1985 to 1992, released a statement via his Twitter account which said: "We are very sad to hear the Saint has passed away.
"Ian St John and I had great fun working on the Saint and Greavsie. He was a lovely man & will be sadly missed by many many people. We must also remember he was a great footballer for Bill Shankly's Liverpool and beyond."
Another former Reds skipper, Jamie Carragher, rates St John as one of the most important players in the club's history, and said: "Legend is a term that gets used a lot but I always think of those players as being the players that started what Liverpool Football Club is all about.
"For me, that makes them the most important players in the club's history. If you think about where the club would be today without those players and the manager and what he did in terms of winning league titles, it was the bedrock of where the club was built.
"It's a sad day. I got to know him really well. I never saw him play but you hear so much about him and my big recollection of him was seeing him at games and as a kid on the Saint and Greavsie show.
"Ian St John, Ron Yeats, and Roger Hunt are the first three players you think of from that 1960s team. Buying him (St John) was one of the best pieces of business the club has ever done."
Current Liverpool boss Jurgen Klopp also added his condolences and reminisced on the time he met St John at their Melwood training base in 2019.
"When you arrive at Liverpool, you become aware immediately of these legends from the time before - and some of them, I have been lucky enough to meet, one of who was Ian," Klopp told Liverpool's website.
"When Ian arrived, it's so funny because you see the pictures of the legends on the walls everywhere, and he looked like he looked like on those photos. It was easy to see, 'Oh my God, yes, Ian St John!'
"He was not only football-wise a legend, but a true legend as a person. It was a pure pleasure to meet him." ❤️— Liverpool FC (@LFC) March 2, 2021
Jürgen Klopp paid a touching tribute to Ian St John...
"He was not only football-wise a legend, but a true legend as a person. It was a pure pleasure to meet him.
"He had a little present with him; I'm not sure it was his first game for Scotland, but it was [a shirt] from a game against West Germany with the number 12. I am now 53 years old so I don't remember 100 per cent who the player was, but in my mind it was Heinz Flohe, a player from Cologne, I think he said.
"It was just outstanding and I'm just so happy to have met him because the best thing you can learn from these legends is how easy it is to stay the person you are, even when you had the biggest success in the past.
"I feel really honoured to have met him and when I heard the news today, I was devastated. All my prayers go to his family and I know he is in a better place as well.
"I am really, really happy I had the opportunity to meet him."
