Former Watford and Northern Ireland u17, u19 and u21 international Josh Doherty has joined Crawley Town on a one year deal with the option of an extra year.
The 21-year-old started his career at Watford and made one senior appearance before moving to Leyton Orient, where he was sent on loan to Altrincham.
Doherty plays as a full back but can also play in midfield.
Head coach Kewell told the club's website: "We're really happy to have Josh on board. He's someone I know well from my time at Watford, he's young, hungry and has both international and domestic experience - so he's a good addition to our squad."
