That turnover from Olmo.
Pedri plays a layoff to FDJ then angles his run smartly into the left half-space. Meanwhile, Olmo drops to link play but misses a crucial second scan before receiving the ball.
The geometry was perfect: a quick 3rd man combo would release Pedri behind Inter's mid.

The buildup to Lamine's goal.

Leading Barça’s attack, Ferran Torres played a crucial role, frequently positioning himself behind the n 10s Raphinha and Dani Olmo to manipulate Inter’s back three.

His smart positioning and well-timed runs were instrumental, eventually leading to the second goal. Videos 👇

This pulls Kounde inside, leaving the left flank open for a late run. Yamal should either track the runner or Kounde should hand him off to a teammate.

Kounde steps up to press Dahl, the left-back, who then finds Schjelderup—now free after creating separation from Araujo.

Like in so many games,many other games, diagonal passes remain vital to Barcelona's buildup play.

As a result, space opened up for Ratiu, as he made a well-timed, unmarked run into Balde’s blind side, attacking the gap with a parallel run.

Simultaneously, substitute Embarba rushed behind Cubarsí to exploit the overload, but the opportunity was thwarted when Cubarsí intercepted the FB's cross.

Isi received the ball in a goal-facing position and expertly released Chavarria into space.
However, Chavarria was unable to capitalize on the opportunity by delivering a decisive pass to his teammates making runs into the box.

Additionally Balde's inability to close down De Frutos allows Rayo to maintain possession and switch play to the opposite flank.
With space and time, Chavarría advances the ball and delivers a cross, but once again, his teammates fail to capitalize on the opportunity.

As the attack advances, Chavarría makes a run into the box unmarked, outpacing Fort to meet García’s cross.

However, due to a heavy first touch, Chavarría miscontroles the ball and fails to capitalize on the significant opportunity.

Lewandowski attempted to adjust by drifting to the wing, aiming to pull CB Lejeune out of position and create space in the center for Raphinha.

However, Rayo Vallecano didn't fall for the tactic: the center-back remained stationed, recognizing that Lewandowski posed less of a threat out wide.

De Frutos outmaneuvered De Jong and played a ball to Andrei Rațiu, who found space behind Balde. Nteka exploited the blind side of Inigo Martinez, while Isi and De Frutos made runs into the box to meet the cross.
However, Szczesny was quick to make a vital save.

Lewandowski’s body orientation enables him to deliver a one touch pass into the space behind for the inverted Balde, who takes advantage of the gaps created by Lewandowski’s movement and Raphinha’s deeper positioning, but the Polish's pass was intercepted.

Here, Acerbi attempts to locate Marcus Thuram in the area behind Koopmeiners. However, Gatti is right there, pressuring him, and manages to get to the ball before the French striker does.
