It was reported on Friday morning that Buvac had left Liverpool, although the Reds quickly clarified to BBC Sport that he was still employed by the club and was only on leave until the end of the season.
Liverpool's preparations for his or her essential Champions League semi-final have been rocked following the sudden departure of assistant supervisor Zelkjo Buvac.
Nonethless, despite having seen his 26-year association with Klopp turn sour, Liverpool maintain that Buvac remains a Liverpool employee and his position at the club is unaffected by this period of absence.
Liverpool fans have taken to Twitter to express their despair that assistant manager Zeljko Buvac will be absent for the rest of the season.
In other Liverpool news, Sky have claimed that the Merseyside giants have already made phone calls about signing BRILLIANT Tottenham player this summer. There will be no official comment from the club due to the private nature of the issue, but the news at the very least raises doubts as to his long-term future at Anfield.
Buvac, 56, and Klopp began their working relationship 17 years ago at Mainz as players, with the Bosnian going on to work as Klopp's assistant at Mainz 05, Borussia Dortmund and Liverpool. Why that?' But it is a decision we come to together.

Over 600 guests have been invited to the wedding , which will take place in the castle's St. George's Chapel, with a further 200 being invited for the reception.
Buvac, then, is clearly a tactical influence on Klopp which, for the short-term, should not present too much of an effect.
In the long run, though, the impact of this breakdown could be more impactful at Anfield.
Buvac has been labelled "The Brain" for his input into coaching and tactics throughout Klopp's management career, who insisted he had to be part of his management team when he arrived at Liverpool in October 2015.
This should not be understated.
In 2013 Buvac also became the head coach of Republika Srpska, the non-FIFA or UEFA affiliated team of Republika Srpska in Bosnia and Herzegovina. Should Jurgen Klopp seek to heal any rift their might be with Zeljko Buvac?
