Former goalkeeper Sander Westerveld has blamed the lack of investment in midfield for Liverpool's problems.
The Reds exited the Champions League on Wednesday as they failed to overturn the 5-2 aggregate score against Real Madrid from the first leg at Anfield. Karim Benzema inflicted further damage on the record as he tapped home in the second-half to put the tie completely out of reach with a 1-0 win on the night.
Jurgen Klopp opted to field four attackers and two midfielders, in James Milner and Fabinho, in his starting 11. Although chances fell to Darwin Nunez, Cody Gakpo and Diogo Jota, they couldn't beat Thibaut Courtois.
