Switzerland vs Italy live updates: Reigning champions knocked out ...

Looking back at the first Switzerland goal, there were two small but crucial details which affected Italy in the build-up.

Firstly, Alessandro Bastoni, who had run across from left centre-back to more unfamiliar territory on the right side of the penalty area alongside Giovanni Di Lorenzo, and Di Lorenzo were both too distracted by the left-wing run beyond Ruben Vargas.

Both had tacked too far to the right in anticipation of the pass being given, and had their arms held out pointing right, indicating the other should cover the runner. In the end, both tracked neither. And Vargas - the attacker on the ball - had too much time and space to pick his pass.

Then, Gianluca Mancini, brought into the team today, threw himself at the ball when Freuler had already got past him.

I'm not saying he should have completely stopped running, but his diving tackle attempt both blocked Gianluigi Donnarumma's view and saw the ball take a slight deflection, changing direction and wrong-footing Donnarumma in goal.

Both contributed to the first goal going in. Those are how fine the margins are.
