Indy Eleven

Haworth can play as a central forward or as a Winger, a position he played regularly for the Fury under Marc Dos Santos, but has also appeared as a right-back. Anticipating a more central role after the arrival of Paul Dalglish, Haworth commented, "Growing up I always played centrally, it's something that comes naturally. For the wingers to be tucked in more and playing closer to goal, it definitely benefits me. I can make those runs in behind and have a little less of a defensive role, so I can save that energy for going forward".
Personal life
Haworth was born in Southport, Merseyside to an English mother and a Welsh father. At the age of one, he and his family moved to Barrie, Ontario.
