#4 vs FC Porto (Last 16)
Liverpool had done all the hard work in the first leg, meaning that the second leg did not really mean that much. This was a comfortable passage to the Reds' first Champions League quarter-final in nine years.
Sadio Mane scored a hat-trick as Liverpool destroyed Porto 5-0 in their own backyard, with some swift counter-attacking football. The entire team stepped up and bossed the game. The heavy win in Portugal meant that Liverpool could breathe easy for the second leg.
The second leg was very uneventful, which is why this is not higher on the list. A professional display ensured that the Reds remained unbeaten in the competition at that time. Danny Ings almost scored his first goal for Liverpool under Jurgen Klopp but was denied by Iker Casillas, who did not play the first leg for Porto.
One of the greatest European nights away from home in Liverpool's history sealed the deal for the Reds.
