I'm a little torn on Hendo playing there, while he won't wander off and get lost like Moreno does, he would probably offer less in attack.
For all his defensive faults - Moreno gets up the flank really well.
I see Hendo playing a deeper traditional left back style (which is probably needed against Arsenal), but I see Klopp wanting more.
Don't move Can out of the deeper central mid position he holds, hes a beast in there.
It would make us weaker trying to strengthen elsewhere.
