When Tang En transmigrated and travelled back in time, he did not inherit much of the original Twain's football knowledge. Therefore, when the original Tony Twain possessed Tang En's old body, he must have brought all of his memories with him. The original Tony Twain was a manager that Paul Hart had held in high regard; that was why he was recommended to become the substitute manager for Nottingham Forest.
However, after Tang En learned about everything, he felt that the original Tony Twain's personality made him unsuitable to become the manager of the team. Paul Hart had valued Tony Twain's ability to train the team, but he had overlooked his personality. And that just happened to become the determining factor for Tang En's decision.
