Posting on X, Carragher said: "Liverpool looking great going forward but susceptible defensively, as we’ve seen all pre-season.
"A lot of the goals conceded by Liverpool have come from going man to man really aggressively and leaving space in behind. Today, Kerkez is getting dragged inside with Sarr, leaving Gakpo chasing wing-back."
After Palace added their second, Carragher retweeted and added: "Again!"
