No penalty. Neil did not “foul” Grosso, he was merely in the way of Grosso’s direction and wasn’t in a position to get out of the away. Also, Grosso just tripped on his own because he misplaced his footing while getting past Neil. Luck was on Italy’s side.

Asamoah Gyan did the same thing against the Italians during the first group stage match and referee used his head and best judgement to not give Ghana a penalty for it.
