Liverpool are mourning the death of one of their great behind-the-scenes figures after Peter Robinson passed away at the age of 86.
Robinson spent 35 years at Anfield after joining as club secretary in 1965.
He witnessed the Reds lift 29 trophies before departing in 2000 having served as CEO, working alongside icons including Bill Shankly, Bob Paisley and Sir Kenny Dalglish.
Jamie Carragher emerged as a first-team regular towards the end of Robinson's time with the club and he took to Twitter to pay tribute to the former Liverpool chief.
"One of the most important figures in Liverpool's success over many years. RIP PBR," the former England defender wrote.
Mark Lawrenson, who won 10 major honours with the Reds in the 1980s, tweeted: "RIP Peter Robinson - Former Chief Executive of Liverpool FC. A true Gent & outstanding Administrator. Big Cricket fan also. A Man ahead of his time."
Is Peter Robinson the unsung hero who laid the foundations for Liverpool's vast success? Have your say in the comments.
Anfield's long-serving stadium announcer wrote: "Sad to hear of the passing of Peter Robinson. This really is the end of an era.
"I was a Kopite when he took over in 1965 and I owe my 50 years working at Anfield entirely to him.
"Liverpool fans are in debt to him for the club they have today. R.I.P. PBR."
Former Liverpool captain Phil Thompson explained how every English team would consult Robinson about "all things" to do with European football in his own tribute.
He added: "Such sad news about the passing of Peter Robinson, he was a behind the scenes legend in how he run our club."
Liverpool outlined just how influential an administrator Robinson was in their statement confirming the sad news of his death.
"Liverpool FC is deeply saddened by the passing of former club secretary and chief executive Peter Robinson, aged 86," the Reds wrote on their official website.
"Robinson was a pivotal behind-the-scenes figure at Anfield throughout a 35-year spell, which began shortly before the Reds’ first FA Cup triumph in 1965, when he joined as club secretary following jobs at Stockport County, Crewe Alexandra, Scunthorpe United and Brighton & Hove Albion.
"In close and constructive partnership with chairman John Smith, he oversaw a modernisation of the club’s administrative operations with the objective of freeing managers to focus on their top priority: winning on the pitch.
"He and Smith were closely involved in player recruitment during an era when the Reds repeatedly achieved masterstrokes in the transfer market.
"And the pair drove forward improvements at Anfield, including a new Main Stand and floodlighting – under which so many special nights would unfold – in the early 1970s.
"It was a set-up that helped to deliver overwhelming success as Liverpool became a dominant force – and trophy-gathering machine – first at home and then on the continent."
