Former Liverpool midfielder Didi Hamann has slammed his old club.
Hamann has criticised Liverpool assistant manager Pepijn Lijnders for releasing a book about Jurgen Klopp's side while still working at Anfield.
Lijnders at the beginning of August released a book called 'Intensity: Inside Liverpool FC'.
Reacting to last night's Champions League defeat at Napoli, 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."
The Reds are due to host Wolves in the Premier League on Saturday as they look to get their season back on track.
