The image of the night in Warsaw on Thursday wasn’t Mario Balotelli ripping off his shirt and, despite his best efforts, failing to keep an ice-cool straight face after he scored the goal of the tournament to take Italy into the final of Euro 2012. It was following the referee’s final whistle. And it involved Balotelli again — of course — as he buried himself deep into the hug of his adoptive mother, Silvia, her face creased in emotion as he whispered that the two goals to defeat Germany were dedicated to her.
