Of course, Buffon knew the ball had gone in!
He stood at the goal line and fished the ball out from half a meter inside, no one understood better than him that the ball had completely crossed the goal line.
In 2011, during the match between Juventus and AC Milan, he performed the same act.
Back then, he managed to fish Muntari's shot out of the goal, so why not do it again four years later against Inter?
Four years ago, Buffon's teammate Vidal had just transferred to Juventus.
He was also involved in that match against AC Milan and personally witnessed Buffon's miraculous save!
If back then Vidal was still a fresh-faced youngster, now he could certainly be called an old hand in football.
So when Buffon shouted and threw the ball at him, Vidal had no hesitation and pushed the ball forward, charging toward Inter Milan's half.
Meanwhile, all the Inter Milan players surrounded the referee, so anxious they could jump!
Vidal didn't care, he kept his head down and charged forward.
