West Bromwich Albion have handed new terms to three young players.
Sporting & technical director Richard Garlick said: "Adil is only 19 and we want to give him the opportunity to continue to develop.
"He was involved in and around the first-team squad towards the end of last season.
"These deals reflect all the hard work the academy continues to do by nurturing more young players onto pro contracts.
Bradley had a successful loan spell at Colchester last season. Mani had a frustrating 2012-13 due to injury and we wanted to give him the opportunity to fulfil the potential he has."
