When Philippe Coutinho left Liverpool in January it was suggested it meant the break-up of the ‘fab four’.

If we take the words of Jürgen Klopp’s backroom team at face value, Anfield is in the midst of another band split with the departure – temporary or otherwise – of coach Zeljko Buvac.

“We are like a music band, each with their own instrument,” was how assistant coach Peter Krawietz, the other key member of the coaching trio, described their relationships to Telegraph Sport two years ago.

“Jürgen is the band leader and others are behind him playing the bass guitar or drum. It is very collaborative how we work. We’ve been this way since we started together. Many years ago a journalist in Germany said I was ‘the eye’ and Zeljko was ‘the brain’ and people repeat it. We could only laugh at this, see it as an invention and say, ‘so what is Jürgen'?

“We are all part of the team here but it is different in Germany to England. Here, as a manager, there are so many more tasks around the club so me and Zeljko try to help as much as we can.”

The idea of Buvac as the “brain” of Klopp’s operation has stuck as a memorable sound bite even if it has been exaggerated for dramatic effect. The Bosnian earned his reputation as a shrewd tactician after Klopp described him as a “master of all kinds of training”.
