I think both Kelly and Wisdom are centre backs long-term, but seems I know very little and they they're being played as full-backs. Wisdom is apparently doing very well at Derby, so we'll see how he progresses as he's still young. Flanagan wasn't a favourite of the fans last season when he looked out of his depth, but this season when he's played he seems to have come on a fair bit.
Skrtel is massively frustrating. Goes from looking clueless and reckless to looking like a top-drawer defender. I think it's to do with who's round him. Agger has gone from the rock at the back to another who lacks consistency.
Johnson is a very strange one. Today it looked like he didn't actually know which way Liverpool were playing at times. Last season he looked very good, far better defensively and a threat going forward. This year he looks...disinterested. Maybe he's carrying an injury?
Mingolet is very worrying. Also, his distribution isn't a patch on Reina's.
Obviously things are better offensively, and couldn't be happier to see Suarez and Sturridge back together again. Loving their bromance

Coutinho is a quality player, but needs to do some serious shooting practice! Sterling is getting better and better, even if he does run like a camp T-Rex. Midfield wasn't great today, but Henderson, Gerrard and Lucas are obviously quality players.
Enjoying watching Liverpool this season far more than I have for a long time. Certainly aren't doing boring at the moment!
