Carroll was firstly loaned and then sold to West Ham in a club record £18 million deal back in 2012/13.
Selling Carroll was one of Brendan Rodgers' first decisions as Liverpool boss and the readiness with which the Reds accepted such a huge loss on the striker cast serious doubts over Carroll's future at the top level.
His time at West Ham has followed a similar pattern with injuries blighting his four years at Upton Park during which time he has managed just 65 games and 18 goals.
The big Geordie recently battled back from his latest long term injury saw him sidelined for eight months only to be injured again soon after his return.
When he came back from that he did begin to look like a force and as if he had found a new level of fitness as he scored and set up some important goals for Slaven Bilic's side.
But he is out for another month after picking up a hamstring injury much to the frustration of the player, Bilic and the club's supporters.
Limited and injury-prone
Now speaking about his decision to move Carroll on after becoming Liverpool boss, Rodgers told Sky Sports' Monday Night Football the striker was too limited and injury prone to play in his dynamic style.
"It (the decision to sell Carroll) was more towards Luis (Suarez) and how I wanted to work," Rodgers told MNF.
"My teams have always been dynamic, always looked to press from the front.
"Andy is a terrific player in his own right and he was at the stage of his Liverpool career where he wanted to play week in, week out.
"He'd been there about 18 months, he'd sort of been in and out of the team, he'd been injured.
"I was very open and honest with Andy and said 'Look I won't be playing with the two up front in that sort of way of working'."
Rodgers was sacked by Liverpool earlier this season and is currently enjoying a break from the game.
West Ham's unreliable Plan B
But his comments will resonate with many West Ham fans who don't believe Carroll can fit into Bilic's own dynamic, freeflowing style of play.
When first choice striker Diafra Sakho is fit Carroll finds himself on the bench but when the stage was set for the former England man to prove his worth in the Senegal's stars absence, he picked up yet more injuries.
Speculation has been rife that West Ham could sell Carroll should the likes of his former club Newcastle show interest, as reported by the Independent.
The Hammers are said to be holding out for as much as £15m.
But with the forward reportedly on around £90,000 per week with another three years of his contract to run, it is a deal which would cost potential buyers upwards of £30m.
For a player with Carroll's injury record and goal return that is a risk many clubs will deem not worth taking.
