Cohen Bramall admits it is "incredible" that he has gone from non-league football and redundancy to joining Arsenal - with the Gunners officially announcing his signing on Tuesday.
The 20-year-old left-back had been on trial with Arsene Wenger's side, with Arsenal having now paid a nominal fee to recruit the former factory worker from Northern Premier League Premier Division outfit Hednesford Town.
Bramall will initially link-up with the under-23 squad after failing to secure deals following trials at both Crystal Palace and Sheffield Wednesday.
Wenger said last week that Bramall, who was made redundant from his job in a Bentley factory a day before signing with the Premier League side, has "similarities to a young Ashley Cole".
