Lionel Messi's wife Antonela Roccuzzo (Instagram)Argentina barely survived Wednesday night at Atlanta's Mercedes-Benz Stadium. Enzo Fernandez pulled the reigning champions level in the 85th minute before Lautaro Martinez headed home in the 92nd to complete a 2-1 comeback over England, and in the stands, the cameras found Antonela Roccuzzo the moment the equalizer hit the back of the net - mascara running, arms wrapped around the person next to her, every bit of tension she'd been holding for 85 minutes finally letting go. Both goals were set up by Lionel Messi, who now leads the Golden Boot standings on assists, though he barely touched the ball in the moment that mattered most - the pass did the work.
