If anyone is stuck for a spot of light reading, 'Jurgen Klopp's Defending Tactics - Tactical Analysis and Sessions from Borussia Dortmund's 4-2-3-1' promises a thorough examination of how Klopp set up his team in Germany, specifically his backline.
On the basis of Klopp's time at Liverpool so far, you get the impression that will be a fairly brief read.
Liverpool are a thrilling prospect going forward, the attacking trio of Mohamed Salah, Roberto Firmino and Sadio Mane offering a brilliant combination of pace, skill and incision. Behind them, when everyone is fit, able and (perhaps most pertinently) willing there's Philippe Coutinho and Adam Lallana to provide creativity and guile. In reserve, there's Daniel Sturridge and the promise of Dominic Solanke and Ben Woodburn.
Watching them attack really is a joy. Most recently the sweeping, lightning counterattacks that brought two of their goals in the 4-0 win against Arsenal were marvellous. Klopp has admitted he regrets using the phrase "heavy metal football" in the past, but this was the game at its visceral, exciting best.
At the back, however, things are a little different. Liverpool have scored eight but conceded the same, the latter number of course swelled by their 5-0 defeat to Manchester City last weekend. That defeat could be written off as an outlier, a heavy loss to a title favourite after being reduced to 10 men. The way Liverpool play, pressing quickly and hunting in packs, they might be the team least set up to cope with a sending off in the Premier League, so it wasn't a huge surprise they were so comprehensively swept aside.
But the problem is that it doesn't take Sergio Aguero and Gabriel Jesus to make Liverpool's defence look vulnerable. Pretty much anyone can. Their weakness from set pieces is well-known, but there's a shakiness during general play that is marked, too.
There are a number of theories for this. A lack of a leader. A lack of a real, world class central defender. Unconvincing full-backs. A midfield that is broadly focused on attack and thus offers minimal protection. Poor coaching.
For his part, Klopp is aware of the problem and is trying to fix it. The omission of Simon Mignolet for the Arsenal game was officially explained as Klopp resting the Belgian keeper, and unofficially attributed to a training ground disagreement between manager and player. But more than that it looked like a manager trying different things to fix the problem. Klopp has made three changes to his back five in each game this season, giving Ragnar Klavan starts, renewing his faith in Alberto Moreno and welcoming Joe Gomez back to the team.
But it doesn't seem to be working and it hasn't for a while. In fact, Liverpool's defence looks barely different than it did when Klopp arrived two years ago. He is clearly a fine manager, but whatever he is trying with Liverpool's defence, for whatever reason, doesn't seem to be working.
So rather than desperately trying to shore things up, to potentially compromise their style of play, why not embrace the chaos? Why waste time trying to fix a problem when two years of trying haven't been successful? Liberate the team and make it as attacking as possible -- even more so than it is now -- with the aim of simply scoring enough goals to negate their problems at the back.
It might not work. History teaches us that a strong defence is required for success in the Premier League. But Liverpool don't have that. Managers should work with what they have, and what Liverpool have is a thrilling, potent attack. Make the most of what they're good at, rather than continuing a vain attempt to make them something they aren't.
Liverpool have the potential to be the most entertaining side in the Premier League. Perhaps even the most entertaining the Premier League has ever seen. If Klopp forgets the defence and goes for all-out attack, they could give us all -- themselves included -- an absolutely remarkable spectacle.
