None of the teams made the difference in the first leg.
The round of 16 second leg of the Champions League, scheduled for this Tuesday, will shake the fans of the 4 major teams competing.
In London, Arsenal host Porto after their narrow defeat (1-0) in the first leg in Portugal.
In Barcelona, the Catalans face Naples who had held them (1-1) in Italy.
First of all, in London, on the eve of their Champions League round of 16 second leg against FC Porto, Arsenal are in a delicate position.
Mikel Arteta's players lost 1-0 in the first leg on February 21, with a late goal that exploded the Dragon stadium in Porto.
Brazilian left winger Galeno found David Raya's side net in the 94th minute with a sudden strike.
Once again, Europe is not giving Arsenal any gifts.
The Londoners will have to force destiny on Tuesday evening, at the Emirates Stadium, to take the road to the quarter-finals.
A stage that the club has not reached since its 2009-2010 campaign, when Robin Van Persie and Theo Walcott passed the leather under the orders of Arsène Wenger.

If this fourteen-year drought weighs on the Gunners, the current group doesn't have much to do with it.
At the start of the first leg, Arsenal had eight players who had discovered the Champions League this season: Bukayo Saka, Declan Rice, David Raya, William Saliba, Jakub Kiwior, Gabriel Martinelli, Leandro Trossard and Ben White.
“When we look at our team, we see that it is a very young group.
Some of us have never participated in the Champions League, we have to learn on the job,” conceded Declan Rice in Porto.
Since their defeat in Portugal on February 21, the Londoners have recovered well in the Premiere League.
Arsenal dominated Newcastle 4-1, then traveled to Sheffield to extinguish the red lantern there 6-0.
This weekend, the London club pocketed a third consecutive success by beating Brentford 2-1.
On the Porto side, the confidence gauge is no less high: on March 3, Sergio Conceição's men corrected the leader Benfica 5-0, before pocketing a 3-0 victory at Portimonense five days later.
This promises a great fight in London.
Naples is a little better, Barcelona counts its injured
The other round of 16 this Tuesday, at the Luis-Companys Olympic stadium in Barcelona, is just as undecided between two injured beasts.
It's an understatement: Naples is going through a worse season than the previous one.
The players of Francesco Calzona - successor to the Italian Walter Mazzarri, who was himself the successor of Rudi Garcia, dismissed last November - are seventh in Serie A, seven points from the qualifying places for the C1.
The reigning Italian champion is snoring but remains hopeful, as he conceded a draw at home against Barcelona in the first leg (1-1).

Both teams are in similar form: Barcelona crushed Getafe 4-0 before sharing the points with Bilbao.
This weekend, Lamine Yamal and his partners beat Mallorca on the lowest stage, 1-0.
On the Napoli side, the 6-1 victories at Sassuolo and 2-1 for the reception of Juventus Turin confirm the “best”.
“The most important match of the year” according to Xavi
Possible key to this round of 16 return, the light in the Barça infirmary is red.
Packages for the rest of the season, Alejandro Balde, Sergi Roberto and Gavi will not appear on the match sheet.
And João Félix, Pedri, Ferran Torres, Frenkie de Jong and Marcos Alonso are doubtful.
Just like Raphina, affected during this weekend's victory against Getafe.
“Raphinha told me it was just a hard blow.
He should be available for Naples,” said coach Xavi at the end of the meeting.
On the other hand, Xavi confirmed this Monday the package of Ferran Torres.
“Our absences are numerous but we have to be competitive.
We were better there (away against Napoli) and we need to be better here, he said.
Absences are not an excuse, we are not afraid to fail, it is a chance to compete in front of our supporters.
» Xavi believes his team is “ready” for what he recognizes will be “the most important match of the year”.
