Plenty would agree that Alves is unique, and he courted scorn for missing the kick-off of tonight's Champions League second-leg at the Camp Nou.
In the other quarter-final tie, Monaco showed why no one will want to draw the French side in the semi-finals with a 3-1 second-leg victory sealing a 6-3 aggregate win over Borussia Dortmund in the principality.
Messi tried his luck from distance - drawing a save from Gianluigi Buffon at the near post - before following up himself to put a second effort into the side netting. "I will remember what happened in the first half there".
Monaco and Juventus now join Madrid duo Atletico and Real in the last four.
Barcelona, with their famed trio of "MSN', huffed and puffed but just couldn't blow away Juve's central defensive pairing of Giorgio Chiellini and Leonardo Bonucci, who were immovable rocks at the back on the night".
However, Barcelona have lost three of their last six Champions League games, as many losses as in their previous 26 games under Luis Enrique.
"The force of the team is not getting too worked up, or shaken", Allegri said.
- Lionel Messi had five shots off target in the match, his most in a Champions League game since September 2015 against Roma (also five).
Macron, Le Pen to face off in second round of French election
Le Pen, who leads the National Front, has made immigration and security a core part of her campaign. "Naivety is over", she said. Although there are 50,000 police on the streets, CNN's Bitterman points out, there are 60,000 polling stations.
It did genuinely seem like it was building up to something at that stage, especially when Messi created something genuinely special with a supreme lofted through ball for Jordi Alba, only for the full-back to just fail to make the right connection.
Andres Iniesta finally gave Buffon a real challenge with 10 minutes remaining, when his glancing effort off a cross made the veteran goalkeeper get down low to save.
"There are still a lot of dangers though, Juve know what the Camp Nou can do". "We now have the chance of getting back in the fight for the title".
"Picking youself up after a defeat like this is hard, but we have the best motivation a Cule can have", Luis Enrique said, "which is visit the home of our eternal rival - there's no better place than to go to than the Bernabeu".
And the only negative news of the night for the Bianconeri was a yellow card for Sami Khedira that will rule the German worldwide out of the first leg of their semifinal.
The result ended Barcelona's run of 15 wins in as many home European matches since the arrival of Luis Enrique, who will leave the club this summer.
- Barcelona have now failed to reach a Champions League semi-final in back to back seasons for the first time since 2004/05, when they went three in a row without one.
