Watch: Bacca slips, gets away with double touch on his penalty

Carlos Bacca was the beneficiary of some good fortune on Sunday.

Amid a wild opening half against Sassuolo at the Mapei Stadium, the AC Milan striker opened the scoring from the penalty spot in the 22nd minute, though upon seeing the replay, it was clear why the home side was incensed that the goal was not chalked off.

As the Colombian slips, his right-footed effort ricochets slightly off his left foot before finding the back of the net; by rule, a penalty-taker cannot touch the ball a second time until it has touched another player - if he does, the spot-kick is meant to be retaken.

The goal was allowed to stand despite Sassuolo's rabid protestations, and the Rossoneri went into the interval with a 1-0 advantage.
