Gabriel Martinelli opened up his body and shifted the neat pass from Bruno Guimaraes into a shooting position. He sidefooted it home, via Zion Suzuki’s fingertips and the inside of the post. Goal, 96 minutes: Brazil 2-1 Japan.Everyone, briefly, lost their minds. The massive yellow bank of Brazil fans behind the goal exploded into an overjoyed mass of humanity: a 96th-minute winner, giving Brazil a 2-1 win over Japan. The Brazil bench emptied onto the pitch, charging to their left to mob the Arsenal forward.Everyone, except Carlo Ancelotti. If you showed someone footage of the just great Italian in that moment, you’d struggle to figure out whether his team had scored a goal or conceded one.

The conversations at half time were about keeping cool heads. We know it’s a long game. And you saw what happened: we kept believing and ended up victorious.”Casemiro, scorer of Brazil’s first goal, concurred. “We felt it too,” he said, when asked about nerves being transmitted from the fans to the players. “We had to patient with the ball, move them around: that’s what I mean by staying calm.“It was a mental test. Japan played in a very deep block, especially after scoring. Finding space against five defenders is hard. The team deserves praise mainly for the mental side, for staying calm. We knew a chance would come.”Brazil’s players celebrate their dramatic winner against Japan (Lars Baron/Getty Images)Being Brazil coach is a uniquely stressful job.

It was hardly a surprise that they snapped.
