Key thoughts and analysis from Champions League round of 16

And then there were eight. The Champions League field has been whittled down once again after the round of 16 came to an exciting conclusion Wednesday. Below, a collection of theScore's soccer editors review the last-16 action, providing one major takeaway from each of the fixtures.

Yamal, Raphinha dazzle for Barca

Barcelona beat Benfica 4-1 on aggregate

Raphinha and Lamine Yamal assisted each other's goals in the 3-1 win over Benfica on Tuesday, once again proving their connection is as smooth as any in European competition. It's not that they simply look for one another but that their sweeping style of play - which leans heavily on dribbling and finding pockets of space - culminates in a cross or pass through the penalty area that lands in their path.

Barcelona could just as easily thump the ball at Robert Lewandowski and hope he converts from range, but head coach Hansi Flick instead asks his talented wingers to make inverted runs into dangerous areas, and they end profiting off each other's trickery. - Anthony Lopopolo

Steady Inter a serious threat

Inter Milan beat Feyenoord 4-1 on aggregate

Simone Inzaghi's team is arguably the least glamorous of the title contenders remaining in the Champions League. But Inter might just be the most dangerous. They lack the mystique of Real Madrid, the youthful exuberance of Barcelona, or the slick interconnected passing of PSG. But what they have, in abundance, is veteran experience, solidity, and robustness.

The Serie A leaders never looked under any threat in their businesslike last-16 dismissal of Feyenoord. They've conceded only two goals in the entire tournament - the best defensive record thus far - and, with Lautaro Martinez and Marcus Thuram, have genuine game-breakers up front. A very similar recipe got them within touching distance of the trophy two years ago. It could carry them all the way this time. - Gianluca Nesci

PSG finally put all the pieces together

PSG beat Liverpool 4-1 on penalties (1-1 on aggregate)

Ousmane Dembele and PSG's forwards - along with a dazzling midfield - get most of the attention, but the French club doesn't reach the quarterfinals without shutting down Liverpool's potent attack over two legs. Liverpool besieged PSG's defense for large portions of Tuesday's second leg after Dembele's early goal brought the visitors level on aggregate. But Liverpool's breakthrough moment never came, and PSG went on to prevail after Gianluigi Donnarumma saved a pair of penalties.

PSG's defensive heroics at Anfield got them to the shootout in the first place. Willian Pacho was a standout performer Tuesday, producing key interceptions, blocks, and clearances. Nuno Mendes also produced critical interventions that were vital in keeping PSG alive in the tournament they're so desperate to win. - Gordon Brunt

Leverkusen crumble against Bayern

Bayern Munich beat Bayer Leverkusen 5-0 on aggregate

Leverkusen hadn't lost any of their previous six matches against Bayern Munich. But that was in domestic competition. "The Champions League is a bit more emotional," Leverkusen manager Xabi Alonso pointed out before the teams' last-16 tie. "Emotional control is most important. Five bad minutes, and you're gone."

Gone they are after losing handily to their German rivals for exactly those reasons. Leverkusen conceded 9 minutes into the first leg and finished the game down to 10 men. Armed with a 3-0 aggregate lead, Bayern struck another two goals while restricting space for Leverkusen to attack. Alonso's side didn't have a shot on target until the 65th minute, by which point the tie was long gone. - Lopopolo

Guirassy keeps swinging for Dortmund

Borussia Dortmund beat Lille 3-2 on aggregate

Serhou Guirassy has been the only constant in Borussia Dortmund's seesaw of a season, and his skillful efforts in Wednesday's 2-1 win over Lille ensured his side's continued progress in the Champions League.

Just as everything seemed to go wrong - a pair of goal-line clearances and a couple of unbelievable point-blank saves unnerved Dortmund in the first half - Guirassy won the penalty that leveled the tie and assisted the goal that won it. He now has 14 goal involvements in the Champions League, the joint-most by an African player in a single season. Guirassy hasn't gone more than two games without having some material impact on the score line, showing the kind of consistency Dortmund have lacked in a year in which they've reached the Champions League quarterfinals while toiling in 10th place in the Bundesliga. - Lopopolo

Asensio adds extra element for Villa

Aston Villa beat Club Brugge 6-1 on aggregate

When January transfers work as intended, they provide a critical midseason boost that can ignite a team and push it over the top. Marco Asensio's move to Aston Villa is a prime example. The Spaniard, who arrived in Birmingham on loan from Paris Saint-Germain on deadline day of the January window, was largely a non-factor in the French capital for the first half of the campaign, scoring two league goals in limited minutes.

But his quality has never been in doubt, and he's reminding anyone who might have forgotten about that. The 29-year-old scored twice in Wednesday's second-leg win over Club Brugge, bringing his tally to seven goals in eight games since joining Aston Villa. Asensio, a three-time Champions League winner with Real Madrid, can bring crucial big-game experience to a club that will now feature in its first European Cup quarterfinal in 42 years. Together with manager Unai Emery, another continental expert, Villa have every chance to continue their unlikely run. To do so, they'll need to defeat none other than PSG, the squad that jettisoned Asensio, in the next round. - Nesci

Arsenal capitalize on rare breather

Arsenal beat PSV Eindhoven 9-3 on aggregate

Arsenal's last-16 affair with PSV Eindhoven played out perfectly for Mikel Arteta. With a quarterfinal berth virtually sealed after a ruthless 7-1 first-leg win last week, the Gunners coach jumped at a rare opportunity to rotate his bruised and battered squad Wednesday. Seldom-used loanee Raheem Sterling delivered a solid first-half display in a makeshift attack that also saw left-back Kieran Tierney start on the wing and midfielder Mikel Merino line up as the No. 9 through the middle.

Arsenal padded their lead to progress with a 9-3 win on aggregate before a difficult quarterfinal test against holders and 15-time winners Real Madrid. But Arsenal's Champions League adventure could get a huge boost by April with Gabriel Martinelli at full strength and Bukayo Saka's expected return. Their Premier League title push is all but over, but don't discount an Arsenal side that could put all their eggs in the Champions League basket. - Brunt

Real Madrid always find a way

Real Madrid beat Atletico Madrid 4-2 on penalties (2-2 on aggregate)

As Atletico Madrid and Real Madrid approached penalties, only one team seemed like the clear winner. Not because they dominated or deserved to go through, but because they have always come out on top. Madrid, of course, obliged, beating Atletico in a shootout for the sixth time in six attempts. An unlucky double touch annulled Julian Alvarez's penalty, opening up the win for Madrid and serving up an excruciating reminder of their historical supremacy over Atletico.

It really felt different when Conor Gallagher leveled the tie on aggregate just a minute into the second leg. Atletico often defended with six at the back but still produced the lion's share of chances, forcing Madrid shot-stopper Thibaut Courtois into seven saves. Even Vinicius Junior missed a penalty, which he had done only twice before in his pro career and never before for Madrid. There wasn't much more Atletico could do. But the Champions League is a funny tournament. Sometimes only the tiniest margins count. And Madrid live in those margins. - Lopopolo
