#5: Dejan Lovren
Lovren arrived at Anfield in 2014, replacing a huge fan favourite in Daniel Agger. So naturally, the pressure on him to succeed was huge - but he has never looked convincing since sealing his £20m move.
Klopp has altered the Liverpool backline significantly during his tenure and surprisingly, Lovren has survived the cut despite being a defensive liability on several occasions to date.
In fact, since joining the Reds, he has made 12 defensive errors in England's top flight alone. Five of which, resulted in goals.
In fairness to the Croatian, he has had his fair share of good performances too but he's just not a reliable centre-back and one that Liverpool should utilise going forward, especially as they have aspirations to challenge among Europe's elite in future.
In truth, Klopp has placed his faith in Lovren on too many occasions and ultimately, it's costing him points. His disastrous performance away against Tottenham earlier this season saw him withdrawn after just half-an-hour, showing why it's important that the Reds focus defensively and acquire better alternatives to avoid Lovren featuring too often if they decide to retain him.
Virgil van Dijk was signed for £75m earlier this window, while Ragnar Klavan and Joel Matip are both capable centre-backs who will be keen to assert their place in the side going forward in future, so Lovren may find himself surplus to requirements.
