Speaking to The Overlap Podcast, Carragher - who made 737 appearances for Liverpool - said: "Might they [Liverpool] regret that [missing out on Guehi]? Listen, they are three games in, nine points from nine and probably not played that well, so we would probably all say they are big favourites, Liverpool. But that is the one area [defence] where that could come back and blow up in their face because they haven't really got that [cover]. What Guehi was getting was giving Liverpool competition at centre-back. They haven't really got that. They've got two starters and two understudies.
"Joe Gomez, injury-prone himself, and the young lad from Italy [Giovanni Leoni], he is going to be a great prospect, but if you think if one of them had to play for a couple of months, it is a big difference."
