Born in Douala, Cameroon, Sousia began his career at the Samuel Eto'o Academy, before moving to Spain to join Barcelona in 2012.[3] However, due to his age at the time of signing, this deal came under scrutiny from international body FIFA, who sanctioned Barcelona for the transfer, handing Sousia a ban until he turned eighteen.[4] He was later told by FIFA that he was unable to train at Barcelona's facilities, nor live on the La Masia campus.[5]
After being kicked out of the club, and made homeless by the FIFA verdict, teammate Álex Collado's family offered Sousia refuge, welcoming him into their home.[5] While staying with the Collados, Sousia trained with Prat, the club Álex's brother, Jonathan, played for.[5] At Prat, he was helped by teammate Federico Bessone and manager Pedro Dólera to settle and come to terms with the situation.[6]
He stayed with the Collados for a few weeks, before moving into the Joaquim Blume d'Esplugues - a residence for athletes.[7] On his eighteenth birthday, Sousia returned to Barcelona, who had been covering his expenses while he was banned.[6][8] However, his return was not seen as successful by his coaches, who told him after three months that he would be sold in the summer.[7] Following interest from Cornellà and Damm, he joined the latter on loan in late 2017.[7]
