Manchester City striker Mario Balotelli is set to be fined another week's wages of £100,000 and given an official warning about his behaviour.
The Sun says Balotelli, 20, will be docked the money after throwing darts at youth team players from a window at the club's training ground.
He was recently fined two weeks' wages for being sent off against Dynamo Kiev.
Now he will also be summoned to showdown talks with Roberto Mancini and a club executive to address his increasingly alarming conduct. City officials had previously been happy to accept Balotelli was merely young, immature and struggling to settle after a summer move from Italy.
But his latest misdemeanour has particularly angered the club hierarchy, who are increasingly beginning to feel the £24million buy from Inter Milan is proving an expensive mistake.
