EKXELLENCE SPORTS is a boutique agency based in Amay, Belgium, created in 2019 by Grace Dieu Diamouangana and focused strongly on the Belgian–Congolese talent pipeline.
The agency specialises in guiding dual-national prospects from Belgian and French academies into professional football, with a growing footprint in Germany, Italy, Scotland and Turkey via moves to clubs such as Werder Bremen, Venezia, Rangers and Kocaelispor.
Its roster leans heavily towards high-upside U23 players, complemented by representation of experienced coach Yannick Ferrera, recently head coach of Zamalek in Egypt and previously of clubs like Standard Liège, Al-Fateh and Omonia Nicosia.
The agency differentiates itself through close links to Belgian academies and the DR Congolese diaspora, plus a willingness to collaborate with partner agencies on complex international transfers, for example in the case of Joseph Nonge.

EKXELLENCE SPORTS’ roster composition and public deals suggest a strategy centred on discovering undervalued dual-national talents in Belgian and French academies, then preparing them for leaps into top-level football in Germany, Italy and other competitive environments.
The agency tends to move players step-by-step (academy to B-team, then to first team and finally to a major move) while collaborating with partner agencies where necessary, instead of forcing early headline transfers. Negotiations, as seen in the Werder–Juventus and Venezia–OH Leuven deals, aim to secure strong sporting projects and long contracts for their prospects.
Typical commissions:
The agency does not publicly disclose its commission structure. In line with FIFA and European FA regulations, representation fees on player contracts in this market are generally in the low single-digit percentage range of gross remuneration, negotiated case by case.
Dual representation:
No explicit public policy on dual representation has been published. Available regulatory filings show Ekxel’lence operating within FIFA and national-FA intermediary rules, which limit and regulate any dual-representation scenarios.
Image rights and expenses:
There is no detailed public breakdown of image-rights handling or expense policies; given the size of the agency and its market, these are likely handled within standard European club–agent frameworks on a player-by-player basis.
Disciplinary actions / sanctions:
No public disciplinary sanctions or FIFA-level disputes involving EKXELLENCE SPORTS or Grace Dieu Diamouangana are recorded in the documents checked.
Litigation / disputes:
No public court cases or high-profile contractual disputes associated with the agency are reported in mainstream or specialist football media.
Media sentiment:
Media coverage is limited but broadly neutral to positive, focusing on successful transfers (Mbangula to Werder, Sagrado to Venezia, Nonge to Kocaelispor) and collaboration shout-outs from partner agencies rather than controversy.
No formal industry awards are publicly listed for EKXELLENCE SPORTS, but the agency has gained recognition for orchestrating Werder Bremen’s record-level signing of Samuel Mbangula from Juventus and for its role in developing several Belgian youth internationals now playing abroad.
