Now that was a proper day of Champions League football.

In the first quarterfinal matchup, Real Madrid and Manchester City finished even at three goals apiece. In the other, Arsenal and Bayern Munich finished even at 2-2. And fans of UCL football were the true winners in it all.

But they weren't alone. Below, we'll break down the winners and losers from a pair of quarterfinal opening legs we won't soon forget.

Winner: Bayern Munich and Manchester City Staying Level Away From Home

Bayern Munich and Manchester City will feel it's a job well done after securing a draw away from home, ensuring they'll have the chance to advance in a week when they host the second legs of what are proving to be brilliant matchups.

It was particularly impressive for Bayern Munich, considering they were banned from having any away supporters for this match after their supporters threw fireworks on the pitch against Lazio. This was an Emirates Stadium filled to the brim with Arsenal supporters and Bayern navigated it with aplomb.

As for City, the club drew away at Real Madrid last year as well before smashing Los Blancos 4-0 at home. It will be hoping for a reprise again this season.

Loser: Arsenal's Defensive Composure

Both of Bayern Munich's goals were heavily aided by Arsenal's sloppiness.

On the first, David Raya unnecessarily came far out of his goal on a long ball forward that Gabriel easily handled, leaving the centre-back without an outlet pass. That sent Arsenal into disarray, Gabriel missed an easy pass, Bayern shot forward on the counter and Declan Rice let a man streak behind him, leading to the eventual Serge Gnabry equalizer.

On the second goal, again on a counter, about three defenders whiffed at the ball before William Saliba committed a penalty in the box, sending Harry Kane to the free spot. He didn't miss.

This was a game that Arsenal controlled rather comfortably throughout, but those two moments of disorganization and sloppiness cost them dearly. The Gunners will need to clean up those types of errors heading into the second leg.

Winner: A Day of Elite Finishing

Put simply, almost every goal on Tuesday was a thing of beauty.

You've seen the Bayern goals already, but here were Arsenal's efforts from Bukayo Saka and Leandro Trossard (with a tip of the cap to Gabriel Jesus' fancy footwork to set him up):

It only gets better from there.

Every City goal on the evening got progressively more impressive, culminating in Joško Gvardiol's absolute stunner:

And while Real Madrid's first goal was a bit fortuitous, benefitting from a lucky deflection, Rodrygo gave Los Blancos a cheeky lead and Federico Valverde nearly disenegrated the ball with his powerful first-timer:

You can't ask for much more than that from a collection of goals. Pure class on display in both games.

Loser: Controversial Calls

From the fun to the frustrating. It just wouldn't be a day of Champions League football without some officiating controversies.

Arsenal, more than any other side, may be feeling aggrieved with some of the decisions that went against them on Tuesday. The first was a Harry Kane yellow for a high elbow that arguably could have been a red:

The second controversial moment came nearly at the final whistle, as Saka broke free on goal and was clipped by Manuel Neuer in the box:

Those in favor of the non-call would argue that Saka was looking for the contact and created it with his run. Those against it would say he made an effort to go around Neuer and was clearly clipped on the leg by the goalkeeper, sending him to the ground.

Bayern were also upset that a potential handball wasn't given in their favor during the game:

If both sides don't have something to complain about in regards to the referee, are you even footballing properly?
