Debrah gives Eastbourne important defensive cover, following fellow centre-half Harry Ransom's summer move to the New Den from East Sussex.

The 19-year-old is now into his second year as a professional with the Lions and has long been a regular in the under-23 side, and will gain experience under Boro manager Lee Bradbury - father of Debrah's under-23 team-mate Harvey Bradbury.

A commanding, physical and composed defender, Debrah converted from an attacking role as an academy prospect at Millwall and was called up to Neil Harris' first team matchday squad in last season's Championship fixture against Bristol City.
