AC Milan want to see extra officials introduced in Serie A games.

The Rossoneri are calling for another match official at either end of the ground behind the goal.

"Everyone makes mistakes," said vice-president Adriano Galliani in his letter published on the club's official website. "But some are very difficult to accept, no matter how much reason and comprehension we try to find.

"I realise technical solutions, which have been proposed by many parties, could still encounter obstacles and not be accepted.

"But I think there is no reason why we cannot adopt the system used in the Champions League."
