UEFA's Control and Disciplinary Body will meet today to deal with the abandoned Milan derby.
The body will convene in Nyon, Switzerland after Tuesday night's quarter-final second leg at the Giuseppe Meazza was abandoned in the 75th minute after missiles were thrown on to the field, with one striking Milan goalkeeper Dida. UEFA says it will announce a decision this afternoon.
Milan, who won the first leg 2-0 last week, had scored a 30th-minute goal through Andriy Shevchenko to lead 3-0 on aggregate but shortly after Nerazzurri midfield player Esteban Cambiasso had a goal disallowed, play was suspended.
Plastic bottles and fireworks were among the objects launched from behind the Milan keeper's goal and German referee Markus Merk decided to suspend the game and take both sets of players off the field and into the dressing-rooms.
An attempt to resume the game was made at 22.40CET but within seconds, further objects landed on the pitch and the referee immediately abandoned the match.
