One of the most significant issues Brendan Rodgers had was in defence. He brought in a number of centre-backs during his time at the club but none of them emerged as a real leader of men or centre-back organizer. Nobody was the next Jamie Carragher. Instead there were the expensive signings of Sakho and Lovren, neither of whom look the real deal. Klopp needs to make signing a top class centre-back his main priority in the January or summer transfer window as Liverpool still look like they can be got at in defence.
2) Up front
Despite the big money signing of Christian Benteke and the addition of Danny Ings Liverpool do not have a great strike force and have not since the SAS pairing. Daniel Sturridge hasn’t got going since then, which has been problematic. Klopp might need to bring in a forward to suit his own style of play. Roberto Fermino was a very expensive support player who Klopp needs to get the best out of. Imprinting his own attacking philosophy will be dependent on utilizing his own personnel, not the dregs left by Brendan Rodgers.
3) Centre midfield
Liverpool have signed multiple midfielders over the years in Emre Can, Joe Allen, James Milner and Jordan Henderson but there is still a feeling that they lack a genuinely top class dynamic centre midfield player. Emre Can has potential but the fact that the side wanted to sell Lucas Leiva implies they need to bring someone else in. Liverpool do not have a firm centre and will need to improve this with a centre-back and a top class central midfielder who can act as a high class replacement for Steven Gerrard.
4) Left back
Liverpool have been utilizing Joseph Gomez as a left back this season. The 18 year old did very well before getting injured but also is naturally a centre-back not a left back. Long term Albert Moreno doesn’t look like the answer either. Klopp needs to bring someone in to act as a long term prospect who can improve the starting line-up and get up and down the left flank like Moreno hasn’t really been able to do due to injury and form.
