It's hard to imagine a better week of Champions League football than we just witnessed.

After Tuesday's pair of scintillating draws, Barcelona beat PSG in Paris, 3-2, while Atlético Madrid held on for a 2-1 victory over Borussia Dortmund.

Neither match lacked for drama. Let's break down the winners and losers from both.

Winner: Raphinha

When you get a brace away from home, helping your side clinch a vital lead in the first leg, you get a winner's section. Those are the rules.

And any time you are mentioned in the same breath as Lionel Messi, you definitely get a winner's section:

He was undoubtedly the receipient of some excellent service from his teammates in the build-up. But Raphinha finished with class, and Barca are one step closer to the semifinals because of him.

Loser: Kylian Mbappé and PSG's Chances to Advance

PSG had a flurry of brilliance in the second half, scoring two goals in two minutes to take a momentary lead.

But other than that, Barcelona often looked the better side on the night. Now, PSG has to travel to Camp Nou and attempt to steal a win to advance. No easy task, that.

To do so, they'll need a far bigger night from Kylian Mbappé than they got on Wednesday.

PSG's disappointments in the UCL are well-documented at this point. They appear headed for another one, barring a major change in form before the second leg.

Winner: Xavi

Xavi's soon-to-be-finished tenure at Barcelona has had its ups and downs, but there's no questioning that he pulled all the levers with his substitutions and tactics on Wednesday.

It was a good night for Xavi. Another one will see Barca through to the semifinals.

Loser: Dortmund's Self-Inflicted Errors

Oh Dortmund, what are we doing here?

Or here?

You can not give teams at this level an easy chance to break with numbers. Those mistakes are killer. You also can't let an Atlético Madrid side that wants to slow down the game and constrict your attacking space an early lead. It's a recipe for disaster.

Dortmund at least pulled one back, giving them hope for the return tie in Germany.

But playing from behind against Atlético is not where you want to be.

Winner: Atlético Madrid's Pragmatic Approach

Look, you may not like the way Diego Simeone has his team play, but there's no doubting that it often works, at least at home.

Granted, a bit of luck was involved too—Dortmund hit the woodwork twice in this match, including with the last touch of the game. And the German side will feel that it handed Atlético both goals on a platter.

But ultimately, the Spanish side came away with the crucial early advantage. It was a job well done at home.
