Castledine had a promising loan spell in League One with Shrewsbury Town last season, making 26 appearances and scoring two goals. However, his season was cut short due to a serious back injury. Now, he hopes to play consistent football for an entire season with Huddersfield and make a decision about his future.

Huddersfield Town has a history of developing young players, with several Chelsea youth team members having successful loans with the club in the past. Castledine will be hoping to follow in their footsteps and grow into a potential first-team player with Chelsea.

Huddersfield Town finished 10th in League One last season, but the club is optimistic about the new campaign and hopes to climb back up to the Championship.
