#3 Liverpool were deserved winners
Atletico Madrid did not register a single shot on target across the 90 minutes, with Alisson practically a spectator in the Liverpool goal.
However, as much as Diego Simeone's men were lacking invention in attack, credit must go to Liverpool for how much control they exerted in the game.
The hosts came up with a game plan and stuck to it from the blast of the whistle. At no point were they ever in danger of relinquishing their firm grip on proceedings.
Jordan Henderson, Fabinho and Alex Oxlade-Chamberlain controlled the tempo of the game from midfield. Meanwhile, Alexander-Arnold was back to his most efficient with his deliveries from out wide.
Even Konstantinos Tsimikas did not look out of place as he deputized for Andrew Robertson on the opposite flank.
In attack, almost everything Mohamed Salah touched turned to gold, and Liverpool should have ended the game with a far more comfortable win.
#2 Atletico Madrid within their right to feel aggrieved by Felipe's red card
Like in the first leg when Griezmann was sent off, Atletico Madrid found themselves reduced to 10 men when Felipe received a red card nine minutes before the break.
The former Porto man was sent for an early shower by referee Danny Makkelie. Replays showed that the decision was a bit harsh. There were also discussions over whether the red card was due to him not answering the referee's initial summons.
Either way, the decision to send off the 32-year-old did not sit well with several fans and neutrals alike.
Atletico Madrid's reduction to 10 men practically put paid to their efforts to attempt to leave Anfield with anything, and this was a sore point in the game.
#1 No love lost between Luis Suarez and the Liverpool fans
Luis Suarez played his way into Liverpool folklore with his performances for the club between 2011 and 2014.
The Uruguay international became an Anfield legend and was fiercely supported by the club's fanbase despite his misdemeanors.
However, things have since changed for the 34-year-old. The last time he came to Anfield was when Barcelona infamously let a three-goal advantage slip in the UEFA Champions League semifinal in April 2019.
His latest return to his former home saw Liverpool fans boo every touch he had on the ball.
Atletico Madrid's toothlessness in attack also meant that Suarez was practically a spectator in the game. He found the back of the net from nothing in the 57th minute. However, the goal was disallowed after a VAR review, which led to one of the biggest cheers of the night.
Suarez was hauled off for Hector Herrera just two minutes later despite Atletico Madrid needing a goal. That pretty much summed up what was a disappointing night for him.
