On 20 March, Rashford made history when he scored the only goal in the Manchester derby, his team's first away league win over Manchester City since 2012; aged just 18 years and 141 days, he became the youngest scorer in the fixture in the Premier League era, overtaking Wayne Rooney's record by almost one year. During the FA Cup sixth-round replay against West Ham United on 13 April, Rashford scored a fantastic curled goal in a 2–1 win to help United advance to the semi-final. Three days later, he scored the only goal of the game against Aston Villa, who were subsequently relegated for the first time since 1987. He later led the line in the FA Cup Final against Crystal Palace on 21 May, which ended in a 2–1 victory marking United's 12th FA Cup win and Rashford's first piece of silverware. He wrapped up the season with 8 goals in 18 appearances, despite only debuting in February, as well as winning the Jimmy Murphy Young Player of the Year. On 30 May, Rashford signed a new contract with United worth £20,000 a week, which would keep him at the club until 2020, with an option to extend for a further year.
