After back to back league defeats, Conte converted into a 3–4–3 formation with Moses playing as a right-sided wing-back in the following match against Hull City. His performance as a wing-back helped Chelsea to a 2–0 victory and also earned him the Man of the Match. On 15 October 2016, Moses scored his second league goal of the season against Leicester City in a 3–0 home win. On 26 November 2016, Moses scored the winner in a 2–1 victory against Tottenham Hotspur and was named the Man of the Match. Moses played 40 games in all competitions for Chelsea in the 2016–17 season, scoring four goals. With Chelsea winning the Premier League title, Moses became the Nigerian player with the most Premier League appearances for a title winning team. Moses courted considerable controversy during the 2017 FA Cup Final against Arsenal which Chelsea lost 2–1. Having been booked for a foul on Danny Welbeck earlier, he was given a second booking, resulting in a red card, after diving in the penalty area. He became the fifth player to be sent off in an FA Cup final. The match was played five days after the Manchester Arena bombing in which 23 people, mostly children, died. Chelsea did not wear black armbands during the first half but did during the second. Then, Moses, while walking off the pitch removed his and threw it to the ground, sparking outrage on social media, with many accusing him of failing to show respect to those that lost their lives.
