Kieran Tierney made his debut for Arsenal and young striker Gabriel Martinelli scored twice as they thumped Nottingham Forest 5-0 in the third round of the Carabao Cup.
Martinelli opened the scoring on his starting debut for the club in the first half, and Rob Holding headed home a second after the break before late strikes from Joe Willock and Reiss Nelson. Martinelli then added his second in stoppage time.
Forest shocked Arsenal in the FA Cup when the met in the third round at the start of 2018, but there would be no surprise result on their first-ever trip to the Emirates Stadium.
