Jurgen Klopp was reportedly left furious at criticism aimed at two of his key members of staff, as the Liverpool manager seeks address his side's dramatic decline this season.
The Reds have endured a difficult campaign and head into the Merseyside derby on Monday in midtable, with the side currently 11 points off the Champions League places.
Liverpool's struggles have been made more dramatic following their stunning displays last season, when they club nearly completed a remarkable quadruple.
The Reds lifted both the FA Cup and Carabao Cup last season, while they fell narrowly short of glory in the Premier League and Champions League.
According to the The Athletic, Klopp has been furious at criticism directed at his staff during this season amid Liverpool's struggles on the pitch.
His assistant Pepijn Lijnders had been criticised by former Reds midfielder Dietmar Hamann earlier in the season, after he released a book while still working at Anfield.
Lijnders at the beginning of August released a book called 'Intensity: Inside Liverpool FC', and it's described as giving 'expert first hand insight into everything from training to tactics and team talks'.
Hamann tweeted: 'The alarm bells should have been ringing for Liverpool fans when the current assistant manager wrote a book while still employed by the club.
'How he was allowed to do it I'm not too sure.'
Lijnders had hit back at criticism, claiming the book 'doesn't give away as much as people think'.
Klopp was also reportedly irked by reports which claimed the club's head of fitness and conditioning Andreas Kornmayer had been questioned within the camp.
Kornmayer has been a vital part of the set-up at the club since joining in July 2016.
Liverpool have struggled with fatigue and injuries throughout the season with star players of recent seasons looking a shell of their former selves.
Klopp revealed at his pre-match press conference on Friday that he had given his side two days off after their 3-0 defeat to Wolves last weekend.
The Liverpool manager said his players looked fresh on their return, while adding the break had 'fixed' his mood.
Klopp had clashed with a reporter following the loss to Wolves, but has insisted he was not disrespectful.
The Reds will target a first Premier League win of 2023 when they face Everton on Monday.
Liverpool had suffered three consecutive away defeats in the league to Brentford, Brighton and Wolves, but will hope to turn a corner at Anfield against their near neighbours.
