Jürgen Klopp already knows what Arne Slot's greatest achievement is since his arrival at Liverpool

There's been a lot of talk about how things have changed at Liverpool since Arne Slot replaced Jürgen Klopp . Perhaps the Dutchman's greatest achievement can be seen when comparing his team's situation to that of Klopp's side at this stage last season.

As detailed in the new documentary ' Doubters to Believers Liverpool FC: Klopp's Era ', this time last year Liverpool were in the midst of an injury crisis. Ahead of the Carabao Cup final at Wembley, Mohamed Salah, Darwin Nunez, Dominik Szoboszlai, Joel Matip, Trent Alexander-Arnold, Alisson Becker, Curtis Jones, Diogo Jota, Thiago Alcantara and Stefan Bajcetic were all ruled out.

That's just one player from an entire squad who is unavailable, and the absence of Salah, Alexander-Arnold and Alisson alone would be enough to make a huge impact , not to mention some of those other names.

Of course, Liverpool would go on to win the final against Chelsea, but it was clear that dealing with the mountain of injuries was taking its toll on Klopp, who by that point had already made clear his intentions to leave the club.

"If young people were to ask me 'what do I have to do to be a football coach?', I would tell them to study medicine first," Klopp says during the documentary.

"Because over the years, you do the job for more than 20 years, you have to make all the decisions. The final decision is always mine, apart from who is fit."

"I don't have the expertise to tell anyone 'no, no, no, he can play'."

Most of the aforementioned players would return before the end of the season, but it would not be an exaggeration to say that the injury crisis had a profound effect on Liverpool's eventual collapse in the Premier League title race. At least the same can be said of Salah, who struggled to reach his usual heights during the latter part of that campaign.

Twelve months on, things couldn't be more different. Yes, injuries are inevitable and Liverpool have had major absentees this season, such as Alisson and Ibrahima Konaté, but since Slot arrived, the Reds' fortunes on that front appear to have changed dramatically.

The Dutchman has taken a number of measures that are specifically aimed at preventing injuries. As detailed by The Athletic , a “body alarm clock” has been implemented into the players’ routine to get players gently moving their muscles as soon as possible.

During training, the players will practice yoga, hydrotherapy and breathing exercises. Training sessions are now longer under Slot than under Klopp, but have become less intense and they spend more time in the gym. The players now sleep in their own beds before home and away games, allowing them to rest better at night.

Of course, there is always an element of luck when it comes to injuries (or, in last year's case, bad luck) and there is certainly no guarantee that if these measures had been in place 12 months ago, Klopp's side would have had more of their stars fit.

But by managing to keep the majority of his squad available for selection for much of this season, Slot has clearly given himself the best chance of success, and the results are there to see. A Premier League title is on the way, the Carabao Cup could be retained next month and, if he can continue to select his best players, Liverpool will be in the race for the Champions League too.
