Wenger hopes he has found a gem in non-league signing

Hednesford play in the Northern League Premier Division, six tiers below the Premier League.

Wenger told the Arsenal website on Tuesday that players who came from such depths had shown they had the mental strength and hunger to succeed.

"It's a mental test -- do you love football enough?," he said.

"Are you ready enough to fight (to show) that you are above this level and that you absolutely want to come back? Players like Giroud and Koscielny have had that test. They are similar to that. Once they get up, they really mean it."

Arsenal's French international Olivier Giroud started out in French lower league football. Compatriot Laurent Koscielny also spent time in the French second and third tiers early in his career.

Arsenal last year tried to sign England striker Jamie Vardy, who has entered soccer lore with his rise to glory at champions Leicester City from non-league Stocksbridge Park Steels and FC Halifax via Fleetwood Town.

Wenger described Bramall, who will join the club's under-23 squad, as a player with "tremendous pace, a good left foot, a great desire to do well. Overall, he's a very exciting prospect."

The youngster was working in a Bentley car factory in Crewe until last month, when he heard he was being made redundant.

"When they told me I was thinking I needed to sort something else quick, I needed more money coming in," he told Sky Sports television.

"But the next day I got a phone call saying Arsenal wanted me to come down for a trial."
