It was in early April that Jurgen Klopp really started to take notice of a striker at Benfica by the name of Darwin Nunez.
As Liverpool's analysis team sat down to pour over the strengths and the weaknesses of their Champions League quarter-final opponents, Klopp was said to have been struck by what he saw from the Portuguese side's star man.
Quick, strong and athletic - plus an eye for goal that would eventually see him finish the campaign with 34 to his name - Klopp quickly "fell in love", to quote one source.
