Speaking on Sky Sports after the narrow victory at Leicester, Carragher admitted that replacing Alexander-Arnold’s unique skill set would be a tall order. However, he argued that the club's transition needs to begin now, with Conor Bradley given a chance to cement his place in the side.
"You can't replace him, because what he is..." he explained. "The reason we talk about him so much, I think why he's the most talked about full-back we've probably ever seen in the Premier League, is because he's unique, he's different. You've [Micah Richards] just mentioned about him defensively, now, most top full-backs don't get it thrown at them that they're not very good defensively. But he's so unique on the ball, I think I said four or five years ago, it's like having Kevin De Bruyne playing right-back, that's what it feels like in terms of his ability on the ball. He can come on and change games, so Liverpool aren't going to replace that.
"So Liverpool need to replace his creativity, they're not going to do that from right-back, they maybe need to that from an attacking midfield position, or maybe a left-wing position. So, the team has to evolve that way. Now, where they can replace him, is Conor Bradley's a right-back. Conor Bradley shouldn't look at Trent and think, 'I want to be like him.' He's got to be like Andy Robertson was when he was in his prime, a proper full-back, up and down, aggressive at the winger, maybe overlapping, getting crosses in, underlapping is what the Liverpool full-backs like to do.
"So you're not going to be able to replace him, so forget that, but the big decision Liverpool have, or a couple of decisions between now and the end of the season, and the summer is...If Trent hasn't committed, which he hasn't obviously, to the manager for next season, he shouldn't be starting games. He shouldn't be..."
