Liverpool have enjoyed a year to remember during 2013, but what one thing would they change if they could go back in time ?
It's always hard to pinpoint a weakness when things appear to be going so well, and that's certainly the case for Liverpool this season, with the Anfield side experiencing their best run of Premier League form in years.
But no team is perfect, no matter how hard they strive for perfection. And Brendan Rodgers' side are far from the complete package.
For all Liverpool's attacking exploits - and the sensational form of Luis Suarez - Liverpool still have plenty of room for improvement - especially when it comes to defending.
So, despite massive strides in the right direction this year, the one thing the Reds would change in 2013 would be the state of their back four.
A key weakness within the red half of Merseyside - one that has persisted for years now - is Liverpool's vulnerability from set-pieces.
This flaw was most recently seen against Manchester City, when Vincent Kompany headed home a first-half equaliser from a corner with considerable ease.
Manchester City (Kompany), Chelsea (Terry) and Arsenal (Mertesacker) all have defensive rocks they can rely on to marshal their troops in times of need, but Liverpool currently have no-one in this role.
The now-retired Jamie Carragher used to be a leader at the back, but the likes of Martin Skrtel and Daniel Agger, for all the good things they have done since moving to Anfield, haven't established themselves as influential defenders.
Agger can't even get into the current starting XI, and his replacement, Mamadou Sakho, hasn't been consistent enough since arriving from Paris Saint-Germain at the start of the season. Kolo Toure's age, meanwhile, makes it likely that he won't be available every week.
Out wide, Liverpool have similar problems.
Luis Enrique's injury has forced Aly Cissokho and Jon Flanagan to deputise but, despite the occasional flash of brilliance from both, neither possesses the kind of consistent quality of a Leighton Baines or even a Patrice Evra.
At the same time, Glen Johnson finds himself virtually unchallenged at right-back, meaning any dips in form simply have to be tolerated.
Which brings us to the crux of the issue: buying a top notch defender.
Although the purchases of Sakho and Toure (especially the latter, who was free) certainly can't be described as mistakes, the Reds may have profited more from singling out a single, top-bracket defender that could have really imposed himself at Anfield.
So, despite a 2013 that Liverpool fans can be proud of, one area that could have been handled slightly differently was Liverpool's back line. And this can be put right in January.
