Jurgen Klopp is irreplaceable at Liverpool.
In terms of what the German coach has achieved on Merseyside since arriving in 2015, combined with his ability to personify the core values of the club and its city, Klopp has been a true perfect fit.
Nevertheless, he will eventually call time on his managerial stint at Anfield and when that day comes, Liverpool will have to be prepared to acquire a suitable heir to his throne.
