Allegedly, Barton was furious when the Newcastle boss told him before the Boxing Day game with Wigan that he was not even on the bench.
Barton/Allardyce Bust Up?
Allardyce said he was worried about Barton's minor ankle injury and wanted to save him for the holiday period games against Chelsea and Manchester City.
It was said that the troubled midfielder flew into a rage and hurled a catalogue of insults at his boss.
Barton is also said to have warned Big Sam he intended to go out in Liverpool that night.
The £5.8m signing from Manchester City stayed out in Liverpool into the early hours of Thursday before he was arrested and charged with assault.
