 In 1999, Forest manager David Platt made Chettle available for loan, and eventually sent him on loan to Barnsley, who like Forest, were struggling in First Division at the time.The two clubs eventually struck a permanent deal after impressing in the two games played during his loan spell.This would then spell the end for Chettle's 13-year Forest career, as he signed for the Oakwell club in December 1999.
