Could Klopp's style be too much for the Liverpool players at the moment or do they just need more depth?
Despite finding some form since Jurgen Klopp replaced Brendan Rodgers at Anfield, Liverpool has seriously suffered this season from a string of long-term injuries to their first-team players.
In fact, things are so bad that Philippe Coutinho, Dejan Lovren and Kolo Toure all picked up knocks during the 1-0 win over Stoke City in the Capital One Cup on Tuesday night - with Coutinho and Lovren both suffering hamstring injuries.
The Reds currently have 10 first-team players out, with Danny Ings and Joe Gomez out for the rest of the season after the pair suffered ACL injuries. But it's the knocks in recent games that will be most worrying for Liverpool fans as they're possibly left with Toure and Lucas Leiva as a centre-back pairing for the next game.
So with Klopp's side picking up so many injuries, what exactly is the reason behind it? Well, former Manchester City and Chelsea fitness coach, Raymond Verheijen, has criticised the German manager's poor judgement.
In a series of Tweets posted by the Dutch coach, Verheijen revealed where Klopp has gone wrong with his players fitness, and it all boils down to his 'gegenpressing' style.
External factor 1. Before Klopp arrived, Liverpool were already struggling with injuries. This in itself is something Klopp could not change— Raymond Verheijen (@raymondverheije) January 7, 2016
External factor 2. In Nov & Dec Liverpool had to play an incredible number of games. This in itself is something Klopp could not change.— Raymond Verheijen (@raymondverheije) January 7, 2016
External factor 3. Players want to prove themselves too much for new manager resulting in injuries. Again something Klopp could not change.— Raymond Verheijen (@raymondverheije) January 7, 2016
Given the injuries & the many games in a short period of time the last thing a manager should do is introduce a more demanding playing style— Raymond Verheijen (@raymondverheije) January 7, 2016
So, is Klopp's insistence to play an extreme pressing style of football the real issue behind Liverpool's injury crisis? Well, it certainly looks that way, but as Verheijen points out, it's isn't down to the German's training methods:
Consequently, the pressing Liverpool players all of a sudden develop much more fatigue during the game compared to previous playing style.— Raymond Verheijen (@raymondverheije) January 7, 2016
Verheijen goes on to say that: "Consequently, the pressing Liverpool players all of a sudden develop much more fatigue during the game compared to previous playing style. This was a massive error of judgement by Klopp as he knew Liverpool had to play more games than any other Premier League team in Nov & Dec
"As a result of Klopp's mistake, the Liverpool players developed more fatigue during games in a period with less recovery time between games. As the accumulation of fatigue is one of the biggest reasons for muscle injuries, the current injury crisis was easy to predict a few weeks ago.
"So, the Liverpool injury crisis has nothing to do with Klopp’s training methods but with the introduction of new playing style at the wrong moment."
With Liverpool's next game in the FA Cup third round against Exeter, Klopp will get a chance to rest some of his players and maybe take a slower pressing style in order to keep players fresh. The Reds still have three Premier League games this month, with two of those being against Arsenal and Manchester United, so the German will have to find a way to ensure his players are 100%.
