Sky Sports pundit Jamie Carragher claimed Liverpool's defence is a concern for the new season.
The Reds were shaky at the back against Chelsea at Stamford Bridge in a 1-1 draw on Sunday.
Despite Luis diaz scoring an impressive goal on the counter, the Reds were pegged back by Axel Disasi.
Reds legend Carragher told Sky Sports: Chelsea are a work in progress. New manager, new players. I think they've been the better team today, there's no doubt about that.
The big worry for me with Liverpool is defensively. The last action sums it up as they had a corner and they nearly conceded a goal at the other end.
Liverpool need a holding midfielder. They need a real defender, an out-and-out defender who can play right across that back four."
