That is the dilemma for national coach Jorge Sampaoli, and although there has been some quality link-up play between the two men in their appearances together for the Albiceleste, it has not really worked out so far.
"Last season in Turin, Juventus played a good game and we made the most of our chances in attack".
Less than 10 minutes into the second half and Lionel Messi nearly doubled his tally for the night and his team's lead.
Barca's start to the season has helped lift some of the gloom around the club raised by losing Neymar to Paris Saint Germain and the failure to sign Coutinho over the summer and the new Barca boss was happy with Tuesday's win. Instead of redeeming himself with a fan base critical of his lack of goals, he missed four clear chances to be the hero after he replaced the injured Benzema in the first half.
As well as the quality of Juventus' attackers, Ter Stegen also admires his opposite number, the evergreen Gianluigi Buffon. After Messi sent a free kick into the wall, Suarez smashed a rocket towards goal from 20 yards, but the legendary Juventus goalkeeper tipped it over the bar comfortably.
Barcelona shutout Espanyol 5-0 at Camp Nou in La Liga with Messi scoring a hat-trick.
Real Sociedad are the only other side with a 100 percent record after the Basque side won 4-2 away to Deportivo la Coruna to go to the top of the table. What this result does is make us understand that if you play in the Champions League against teams of that level and don't keep your concentration, then you pay for it.
Yet, having lost in the final in two of the last three seasons to Barca and Real Madrid, Allegri insisted the Spanish giants remain favourites to win the competition again.
"[Buffon] is playing at an age at which many have finished their careers and he looks like he's 30 and in his best years".
Barcelona vs Juventus match is one of eight games today on September 12th Tuesday.
Messi was far from done.
Tottenham star Dele Alli is already being investigated by Fifa for making the same offensive gesture during England's World Cup qualifying win over Slovakia earlier this month.
