Daniel Rhodes and Paul Dalglish look back at Liverpool's fantastic five-two win over Roma in the first leg of the Champions League semi-final, topics include: what are the strengths and weaknesses of the 3-4-2-1 system Roma deployed, and what could their manager have been thinking in seemingly playing into the Reds' hands; What were the possible options to contain Liverpool? The utter brilliance in transition, creating one v one duels on their back three with space to run into; Salah's finishing - and how his relaxed manner is crucial; how do you defend against him? Going over the goals and key chances; should we have gone more defensive at five-nil? How much rotation is required before the second leg?
