Barcelona's defense isn't good enough to carry Lamine Yamal through a serious Champions League campaign. Tuesday night in Paris made that plain. PSG won 4-2, Barcelona twice clawed back to level, and the thing that decided it was the thing everyone in Spain has been nervous about for weeks: a back line that leaks against the best teams on the planet.
Start with what was right, because it was genuinely special. Yamal scored in the 79th minute, drifting behind the PSG defense and finishing past Safonov to make it 2-2, a goal only a handful of players alive could produce. It put him level with Kylian Mbappé for the most Champions League goals by a teenager. He was Barcelona's best player and their safety net at the same time. That's the problem. You shouldn't need your 19-year-old winger to bail out the result, and on this night even that wasn't enough.
For every moment of Yamal brilliance, the other end coughed up a gift. Doué opened the scoring after Barcelona lost the ball. Vitinha restored PSG's lead two minutes after Yamal's equalizer with a superb strike. Fabián Ruiz finished off Hakimi's cross late. Joan García kept the scoreline from turning humiliating with a string of saves that flattered the defenders in front of him. When your goalkeeper is the reason it's only 4-2, the back line has already lost the argument.
This sits with Hansi Flick. He rested Rodri with Sunday's Clásico in mind, started Marc Bernal in midfield, and went into the biggest night of his season so far already missing Eric García and Jules Koundé at the back. Dani Olmo limped off in the first half on top of it. He chose freshness for Saturday's fixture and fielded a defense short-handed against the team many now rate as the best in Europe. The calendar is brutal. But you don't get to pick a lineup built for Saturday and then act surprised when Tuesday punishes you. Four goals is the punishment, and even critical accounts of the night called at least two of them avoidable.
There's another side to this. Barcelona went to Paris on an 11-match winning run across all competitions to start the season, lost to the reigning champions, and twice refused to lie down. That's a team with some steel in it, real quality in a side that can get hit and keep punching back. But that fight never turned into control. Fighting level twice is only impressive because the defense couldn't protect either equalizer, letting PSG retake the lead both times. Resilience got them through a rough night, but it doesn't fix the structure that put them in one.
The captain more or less said it himself. "We were hoping for a win or at least a draw, but now we have to see what the coach tells us we need to improve," Raphinha said after the match. He's pointing at the dugout. He's right to.
This is one night, Matchday 3 of an eight-game league phase. PSG sit top with nine points from three games; Barcelona are fifth on six, their first defeat of the season. There are five more league-phase games to fix it, and talent this good deserves the benefit of the doubt over a full campaign. But the diagnosis is already clear. Yamal will keep producing nights that should win games. Until Flick stops picking a lineup for the fixture after the one in front of him, Barcelona will keep losing them anyway.
