Steven Gerrard and Jamie Carragher shared a special bond during their time together at Liverpool.
Teammates on the pitch and friends away from it, the English duo started out as exciting prospects on Merseyside in the 1980's and went on to achieve greatness.
After making the step up to Liverpool's first team, they won the UEFA Cup in 2001, the Champions League in 2005 and two FA Cups.
All the above makes today a very sad day for Liverpool fans. Gerrard has called time on his illustrious career three years after Carragher did the very same.
The legendary Reds captain released a statement to announce his retirement, with fans, former teammates and fellow professionals alike paying homage on social media.
Carragher wasn't one of them, though. Instead of dedicating an individual tweet to Gerrard, he had little more to say than "spot on, now he can join me on MNF" in response to BT Sport's tribute (see below).
Carragher did spare a few words for Gerrard in an interview with Sky Sports, where he reflected on the 36-year-old's achievements and named his 'favourite Steven Gerrard moment'.
"I think the goal in Cardiff, against West Ham," he said, per the Mirror. "Last kick of the game and we're about to lose the FA Cup final.
"He shoots from 35-40 yards, anyone else you'd be screaming, but Stevie pulls out something unbelievable. He carried us in that final."
In case you've forgotten - and how could you? - here's the goal Carragher refers to.
The former centre-back also lauded Gerrard's heroics in the 2005 Champions League final against AC Milan, where Liverpool came back from 3-0 down to win on penalties.
"His second half performance was inspirational," Carragher added.
"He scored the first goal back and then on his way back to the halfway line, he really lifted the crowd. I’m sure that will be what he's remembered for.
"He carried the team to the trophy and played three different positions on the night.
"If Shevchenko hadn't missed that penalty, I'm sure he'd have won it anyway."
And on what the future holds: "Stevie's mentioned that he wants to look at management, coaching, 18 months down the line, I’m not sure.
"He's on about getting his badges, and being as qualified as he can possibly be, because there'll be a lot of eyes on him.
"He was an inspirational figure. If he can take that into coaching, he'll be fine. I'm sure he can be that off the pitch as well."
