WEYMOUTH have inserted a sell-on clause in Omar Mussa’s contract at Dagenham & Redbridge, Echosport understands.

It means Weymouth will receive an undisclosed percentage of any future sale of Mussa by National League side Dagenham.

Mussa, 21, was officially announced by the Daggers yesterday as the Londoners beat a host of other clubs to his signature.

Belgian midfielder Mussa was close to signing for Southend and even had a medical with the Shrimpers, according to sources close to that failed deal.

Weymouth are believed to have had financial reservations over the move and negotiated terms with Dagenham at the final hour.

Weymouth have earned a significant five-figure sum for a player that scored just once in 37 appearances last season, plus contributing four assists.

Dagenham have finally got their man after a bid was rejected by the Terras in January.

Daggers’ boss Daryl McMahon yesterday said his club had made “numerous bids” for the former Walsall playmaker.
