Mario Balotelli's off-field antics stepped up another notch on Tuesday afternoon when he barged in uninvited on new Inter boss Andrea Stramaccioni's first press conference. The Manchester City star parked his Ferrari outside the building, strode in unexpectedly, shook hands with the coach and the Inter directors, and then left just as abruptly as he came.

The incident is the latest in a long line of unpredictable shenanigans concerning the volatile 21-year-old, who has created more headlines off the pitch than on it in his short career.
