The Reds have spent big money improving this summer, but Parlour still has a doubt.

The Reds have been busy this summer, as seven new signings have arrived at the club so far.
The big money has been spent on improving their forward line, with Sadio Mane and Georginio Wijnaldum both arriving for lofty price tags.

Jurgen Klopp has also moved to improve his defence, although the deals for both Joel Matip and Ragnar Klavan have been much cheaper than those for their new forwards
And Parlour believes that the defence is still an area that they are lacking in.
“They’ve got good players with lots of options up front,” he told talkSPORT.
“Defensively is probably where they are lacking but I think they will be organised as usual. Klopp has had time to look at the defence and assess whether they’re good enough.”

It remains to be seen if Klopp does believe that his current options in defence are good enough or if further signings are needed.
It is fair to say that the position has been a problematic one for the Reds for several years with it particularly hampering them during Brendan Rodgers’ reign.
So far they have avoided a big name signing to try to fix it and it will be interesting to see if Klopp decides to change that stance before the end of the window.
