Buvac, who has been Klopps assistant at Mainz, Borussia Dortmund and Liverpool, has temporarily left his role due to personal reasons.
Reports had initially claimed that Buvac was involved in a bust-up with Klopp and has left his post, but Liverpool insist that the 56-year-old remains employed by the club.
Asked about Buvacs absence for Liverpools fixture against Roma, Klopp said on Tuesday: We gave a club statement to that, thats all what we are saying at the moment, nothing else.
Liverpool midfielder Georginio Wijnaldum also refused to speak about Buvacs absence.
Its something for later, said the midfielder.
Im here to speak about the game and not other things.
