The 19-year-old caught the eye of Aduana's scouts during the 2017 Wafu Cup of Nations held in Ghana but an initial bid from the Dormaa Ahenkro-based club was rejected.
However, with Aduana qualifying to the group stage of the Caf Confederation Cup and Boubacar having the chance to play on continental level, the player reached an agreement with his former club to accept the improved offer.
We are happy to announce the signing of Hainikoye Soumana Boubacar aka "Deco" from USGN, Niger. He has penned down a two year deal with the #ogya family. Welcome Soumana and enjoy your stay at Mmanim. Together we made it. ADUANA! OGYA!!🔥🔥🔥🔥🔥🔥 pic.twitter.com/C65dXplneO
