According to the Mirror, the defeat means United, on seven points, have suffered their worst start to a Premier League campaign since 2004, when they picked up just six points from their first five games.
Moyes was in no mood to spare his under-performing United players from his anger after revealing he told them their abject display was unacceptable and that he wants a reaction, the report said.
However, the new boss said that every manager has bad results and he was no different.
He said that United had good players but he was disappointed that the team did not perform.
After drawing 0-0 with Chelsea at home and losing 1-0 at Liverpool, defeat away to City has increased the pressure on Moyes, 84 days into the United job, the report added.
