Centre-back has been the area subject to the most rotation under Steven Gerrard.
It’s now January, and it still isn’t totally clear what the best partnership is at the heart of this team’s defence.
What is certain, is that Connor Goldson’s a shoe-in.
The summer signing and vice-captain, has excelled all season. He arrived and instantly made the spot his, racking up 36 appearances so far.
However, he has struggled to find a long-term partner.
Nikola Katic played frequently across the early season.
The Croatian looked a great asset before losing his way and his place in the squad, back in November. He has barely featured since.
When Gareth McAuley finally overcame a calf problem, he looked to be nailing down his spot.
Yet, just as he looked to be growing in confidence, he suffered another injury set-back, ruling him out of the final few matches ahead of the winter break.
Worrall could be the answer
One man who has been around throughout all of these issues, is Joe Worrall.
I’ll admit, I wasn’t sold on him initially.
He started steadily, but then lapses in concentration and lackadaisical distribution saw him deservedly dropped.
He had arrived with a big reputation, but didn’t quite seem fully focused.
That is, until last month’s Old Firm. He was magnificent on the day and worked well in partnership with Goldson.
Worrall frequently stepped up to cut out Celtic attacks in their early stages, while his partner covered in behind.
Based on that showing alone, these two deserve the nod going into 2019.
Should it not work out, Gerrard can be safe in the knowledge that he has like-for-like replacements.
Worrall should get first crack, though. He’s earned it.
