The Reds ran out 1-0 victors over their archrivals after a howler by Jordan Pickford gifted substitute Divock Origi a late winner, thus, marring a great performance from the England goalkeeper.
Pickford had kept the hosts at bay, thwarting several goalscoring chances and stood in the way of Mane who was particularly wasteful on the evening. But it was his attacking partners Salah - unable to break a 120-year record - and Firmino that were hauled off for Daniel Sturridge and matchwinner Origi respectfully.
Asked about the reason for the decision, and if it was a signal that he would be rotating his team more often, the German tactician said: “We will see what we do, but it was such an intense game.
“Sadio had the standout performance of the three. Yes he had the chances and he didn't use them, but he was pretty much not (easy) to defend in one-on-one situations.
“He got better minute by minute. If you see now he is sitting in the dressing room and has a cut on his foot. Twenty minutes from the end he got it, I don't know how it happened but it was a very painful thing.
“He didn't tell me, otherwise we may have changed [the substitutions] differently. Probably not.
