Liverpool insist assistant manager Zeljko Buvac will return to his role alongside Jurgen Klopp at Anfield - despite reports in the Bosnian media he is in line to succeed Arsene Wenger at Arsenal.
Buvac, nicknamed 'the Brain' by Klopp, has temporarily left his role for personal reasons - Sky Sports News in Germany understand he is currently in Mainz where he first teamed up with Klopp back in 2001.
Sources in Germany also understand Klopp and Buvac have had a disagreement although further details are unclear and Liverpool's position has not changed since the club clarified their stance on the Bosnian's departure on Monday.
Liverpool say Buvac remains an employee at Anfield and his position at the club is not affected by this absence.
Klopp refused to discuss Buvac in his news conference ahead of his side's Champions League semi-final tie against Roma.
The decision was taken by Klopp and Buvac over the weekend to temporarily suspend their working relationship and because it is a personal matter, the club will not comment any further on the issue.
Klopp will be without his long-term assistant when the squad train in Rome later on Tuesday as they prepare for their decisive Champions League second-leg against Roma on Wednesday. Liverpool are 5-2 up on aggregate.
