Due to the break in the 2019–20 Premier League season due to the COVID-19 pandemic in the United Kingdom, Smith was called up by the Arsenal head coach Mikel Arteta to train with the first team. He would later be named on the bench for Arsenal for their Premier League match against Southampton. He would continue to be named on the bench for the rest of the season but never played. He was also named on the bench for the 2020 FA Cup Final which Arsenal won and earned Smith a winner's medal despite not having made his first team debut for Arsenal.
