Liverpool manager Jurgen Klopp praised hat-trick hero Sadio Mane and his side's "perfect" performance after they all but booked their place in the Champions League last eight on Wednesday by thumping Porto. The five-time champions romped to a 5-0 victory at the Portuguese league leaders, and when asked if Liverpool had put in a perfect performance, Klopp told BT Sport: "Yes. You could say that of course. "It was very professional, very mature in the right moments, very aggressive, good defending, good counter-attacking, keeping the ball, moving them around. "In this game it was possible, usually it's not that easy."
