Graham said on the documentary, How to Win the Champions League: Liverpool 2019:"Jurgen's preferred option for that summer was Julian Brandt, who was a great player. Jurgen would obviously know him very well coming from the Bundesliga and knowing the German market very well. We agreed that Brandt was a very good young player but not a standout in the same way that Mo was. From our data analysis point of view, Mo was the best young wide forward in Europe full stop. Roma were under pressure to sell because their finances were not in a good place so we knew he was available for a good price. He played a forward and wide role that we needed to fill at the time whereas Brandt was more of an attacking midfielder. It's to Jurgen's credit that he engaged in that debate in an honest way with his eyes open to say, 'OK, I'm open to be convinced, show me that Mo is better'."
