Charlie Adam says Jurgen Klopp needs six new players in the summer
Klopp, who failed to bring anyone in during January, has seen Liverpool win just one of their 10 games since the turn of the year – against League Two side Plymouth in an FA Cup replay.

The former Anfield midfielder reckons Klopp is in desperate need of a new goalkeeper, with both Loris Karius and Simon Mignolet struggling for form this term.
Adam has been impressed by midfielder James Milner's performances at left-back, but believes a natural full-back is required next season.
The Scotland international, who lasted just one season at the Reds before joining Stoke in 2012, also wants to see another midfielder, striker and a couple of wingers at Anfield.
