What Liverpool need this season

Liverpool have already acquired 6 players in this transfer window with the likes of Danny Ings, Roberto Fermino, Adam Bogdan, Joe Gomez, James Milner and Nathaniel Clyne and also with the impending arrival of Christian Benteke, so what else does Liverpool need this season to complete the squad and compete for silverwares??
1. Liverpool need a new quality Centre Back as last season high profile signing Dejan Lovren failed to live up to the expectations and there is no guarantee that this year will be any better than the last. There is still questions regarding the partnership of Skrtel and Sakho so Liverpool still need a quality CB to partner Skrtel at the heart of Liverpool defense and bring some leadership there which we desperately need after the retirement of Jamie Carragher.
2.Liverpool need a solid defensive midfielder after the huge hole left in the middle of the park with the transfer of Stevie G. Liverpoolhave players such as Lucas Leiva, Joe Allan and Emre Can to cover the area but I really doubt the quality of Lucas and Allen and I still think that Can is one for the future. Maybe in a couple of season he can be the box to box central midfielder but for now we really need to bring someone in who can take controll of the game and start the attacks from the middle.
