Query for arsenal historians.
I went to school with all hannigan who played in youth team of 87-89 and didn't make any first team apps but had an OK career at a lower level. But in my year there was a kid Elliott batt who claims on various social media that he was also an arsenal youth team player 88 and then went on to play for Celtic and averely. I can't find anything on the Internet to back up Elliot's claims. Anyone remember him or know one way or the other if he was ever at arsenal?
