Liverpool coach Pepijn Lijnders has hailed the impact of Zeljko Buvac.
Buvac arrived last season along with manager Jurgen Klopp.
Lijnders told liverpoolfc.com: “The boss called him a coaching book. I call him a coaching computer – unbelievable.
“I am doing the pro licence in Wales but I feel that this is the pro licence plus, plus! It's his knowledge about the past.
“But this is something special.
“Because you grow up and your passion and ambition as a coach, your character, the way you look at the game and the way you see your team playing – I identify myself so much with the style. All the people in Holland and Portugal who saw my teams play know that."
