Jurgen Klopp has spent seven FA Cup campaigns having his attitude questioned by the traditionalists, but he will surely not hear of it anymore after Liverpool booked their place in the semi-finals here in Nottingham.

Klopp's feelings towards this competition have often been probed with regards to how he views its overall importance in the grand scheme of a Liverpool season.
