The 24-year-old's future appears to be in doubt as Liverpool are seemingly keen to offload the frontman in the summer when he finishes his season-long loan deal at West Ham United.
"I think he could do a good job at Liverpool, I really do," Roberts told talkSPORT. "I don't agree he is just a big target man.
"There is more to his game than that. He can hold the ball up, he's got a terrific strike with his left foot, he's got a good touch, he brings people into the game.
"I can't help but think that he can fit into that Liverpool side, with [Luis] Suarez on one side and [Daniel] Sturridge on the other. I think whoever gets him will be getting a tremendous player."
West Ham boss Sam Allardyce has admitted that he wants to keep hold of Carroll but financial restrictions may prevent a transfer from going through, while Newcastle United are also thought to be interested.
