Sanson remembered how things were going well at the club when Dean Smith was in charge. However, everything changed when Gerrard took over in November 2021. At first, things seemed fine, but Sanson soon faced challenges.

He contracted COVID-19 twice and suffered a quadriceps injury. The turning point came during a match against Manchester United on January 15, 2022. In his first start in a while, Sanson played well but made a mistake that led to the opponent's goal. He was taken out of the game immediately.

Feeling frustrated and angry, Sanson reacted by throwing bottles and kicking water bottles. He described the situation as a "disaster." After the game, Gerrard asked Sanson to explain himself, but Sanson felt that Gerrard didn't believe him.

Trying to clear up the misunderstanding, Sanson had a direct conversation with Gerrard the next day. He went to Gerrard's office and looked him in the eyes while explaining himself. Gerrard seemed to understand and told Sanson that he was the best midfielder he had and that he was only taken out of the game due to the mistake.

However, Sanson didn't play for six weeks after that. He realized that Gerrard's words were empty and that their relationship remained strained. Sanson returned to the field on February 26 against Brighton, but the tension between them persisted until Unai Emery took over in November.
