Point 1, they rested
all of their star players. Players like Mooy, Schindler, Lowe, van la Parra and Wells have started almost every game, whereas Bunn and Holmes-Dennis were making their 5th and 3rd starts of the season. It is fine to rotate but when you chuck an entire squad of players that have barely played, you regularly get results like Saturday.
Point 2, they have 2 wins out of 24, before Saturday. So before that, they'd won half their games. Birmingham have been awful post Rowett, and they were given an easy task.
Point 3, Manchester United played the weakened side, allowing West Ham to win and relegating Sheff Utd.
