Another obvious one.
Liverpool's transfer policy over the past year has been questionable, to say the least. Babel, Torres, Aquilani and Meireles have all been either sold or forced out of the club in the last year, and with the exception of Luis Suarez, the replacements for those four attacking players have fallen well short of the mark.
Sabermetrics is the name of the game when it comes to Liverpool's transfer strategy under Damien Comolli.
Andy Carroll was signed from Newcastle United for £35 million as a replacement for Fernando Torres in a move which reeked of blind panic. Carroll was signed off the back of one good run of form which saw him score 11 goals in 19 games.
Now, some Liverpool fans will point to that impressive run of form and claim that it is proof that Carroll has great ability, great potential and is a great goalscorer. I will point to Michael Ricketts as proof that one good run of scoring in your first full Premier League season means nothing in the long run.
Ricketts was actually more impressive than Carroll in the Championship and Premier League with Bolton Wanderers. Not only did he score a lot of goals, he made a lot of goals, too. He played for England, just like Carroll. Then his true talents shone through, and he was last seen playing for Tranmere Rovers nearly two years before being released. He has been without a club, or the interest of a club, since.
For fans of sabermetrics, Carroll did represent a good signing, transfer fee not withstanding. His chances to goals ratio at Newcastle was pretty impressive, as long as he got his shot on target, of course.
In a season and a half with Newcastle before his move to Liverpool, Carroll took a total of 171 shots at goal. Unfortunately, only 60 of these actually managed to go in the direction of the goal. What was encouraging is that of those 60, 30 resulted in goals.
The answer seemed simple for those with sabermetric inclinations: Sign players who create a lot of chances and Carroll is the man who can convert them at a high rate. For a further £49 million, Liverpool added Jordan Henderson, Stewart Downing and Charlie Adam.
All three ranked among the top chance creators in the Premier League the season before, and Adam's prowess from deadballs was also seen as a great opportunity to make use of Carroll's dominance in the area.
The system was built, the system was tried, the system has failed. Two league goals from Carroll thus far this season, as well as a couple of goals in the cup competitions against League One opposition, is quite frankly, a pathetic return for such an expensively assembled experiment.
Even when you factor in the goals and assists of Downing, Adam and Henderson, they still don't come close to being acceptable statistics, and the performances have been just as poor.
Some will claim that Carroll has not had enough time on the pitch, and that's the reason he hasn't delivered. 14 starts and 10 substitute appearances is more than enough time on the pitch when you're not earning your keep.
Others will claim that Carroll has not had the service require to score goals. 42 shots on goal in the league, with 14 on target, suggests that he has had far better service than has been suggested.
There might be some offset if Carroll was working hard for the team, displaying the correct attitude or improving week after week, but he's not. And in all three cases, far from it.
It's not just Carroll, of course, but he is the biggest and most expensive failure of the lot.
Downing was overpriced and has flopped thus far, and both Henderson and Adam have failed to live up to the billing.
But Downing is at least working hard for the team, Henderson has shown signs that he can be a major player for Liverpool in the long run and Adam is both working hard and providing goals and assists, which is about as much as you can ask for £8 million on today's market.
Liverpool must address their strategy in the transfer market and should spend more time focusing on players who can bring the best out of Luis Suarez and Steven Gerrard, rather than buying people to make Andy Carroll look good and expecting Suarez and Gerrard to do it all by themselves.
THE BRIGHT LIGHT:
Luis Suarez, Jose Enrique and Craig Bellamy have all been excellent, and signings of young players like Jordon Ibe, Seyi Ojo and Joao Carlos ensure that the club has a bright future.
