The referee began to usher the Arsenal players back, clearing the penalty area.
The tension was thick enough to slice.
And as Marquinhos stepped back, the camera caught Izan standing near the edge of the box, biting the inside of his cheek, watching.
Waiting. The match had not even fully settled.
But now PSG had a golden chance to strike first and strike fear into the hearts of the Arsenal faithful.
The Emirates fell into an eerie hush as Marquinhos stepped up to the penalty spot.
"Here comes the PSG captain," Darren Fletcher said, the tension rolling in his voice.
"A chance to silence this North London crowd early. Raya bouncing on his line..."
The Brazilian took a slow breath, shoulders squared, with his eyes fixed on Raya.
The whistle blew and Marquinhos surged forward, striking cleanly to his right, but Raya guessed it, diving with full extension and palming the ball wide.
