Both Nelson, 17, and Willock, 17, have risen through the Gunners’ academy ranks from a young age while 21-year-old defender Bramall arrived at the Emirates from Hednesford Town after a successful trial back in January.
All three youngsters were included in Arsenal pre-season tour of Australia this summer and have been rewarded with places in the side’s first-team set up for the 2017/18 campaign.
Nelson, in particular, was one of the success stories of Arsenal’s pre-season and impressed against the likes of Bayern Munich, Chelsea and Benfica.
The promising teenager will wear the No. 61 shirt this season, while Willock will don the No. 69 and Bramall takes the No. 40 shirt.
Following Arsenal’s 5-2 win over Benfica in the Emirates Cup, Wenger said of Nelson: ‘He’s a player from our academy.
‘He’s had an encouraging pre-season. He’s shown you can go past people. He’s not fazed. It’s good for his confidence levels.’
