# RSC Anderlecht leadership restructuring > Live situation record from CLSTR: https://clstr.news/situations/rsc-anderlecht-leadership-restructuring > Updated: 2026-08-01T18:16:04.000Z. Sources: 3. Developments: 2. On July 31, 2026, Belgian club RSC Anderlecht announced a major internal overhaul. Jonas Geleyn was appointed Chief Commercial Officer, bringing two decades of multinational experience, and was tasked with overseeing marketing, sales, partnerships, ticketing, match operations and technology. At the same time, sport director Antoine Sibierski was given “all‑in” authority over the first team, the Futures squad, the women’s side and scouting/performance, with decision‑making lines shortened to streamline the club’s strategic ambitions. A day later, on August 1, 2026, Sibierski’s impact became evident. Known for a strict, direct‑communication style, he conducted a rapid review of the senior and youth squads, identified defensive weaknesses and moved quickly to sign defenders Giulian Biancone and Léo Pétrot, as well as midfielder Lukas Ambros. The swift recruitment drive reflected his reputation for turning around teams, echoing his earlier success at French club Troyes. Together, the appointments and immediate actions illustrate Anderlecht’s shift toward a more centralized, decisive management model aimed at strengthening on‑field performance and commercial growth. ## Timeline ### 2026-08-01: Antoine Sibierski imposes strict regime at RSC Anderlecht Antoine Sibierski, dubbed “Darth Vader”, becomes RSC Anderlecht’s sporting director, enforcing a direct, no‑compromise style and bolstering the squad with defensive signings such as Biancone, Pétrot and Ambros. 2 sources. https://clstr.news/cluster/antoine-sibierski-imposes-strict-regime-at-rsc-anderlecht ### 2026-07-31: RSC Anderlecht names Jonas Geleyn CCO, gives Sibierski all‑in authority RSC Anderlecht has hired Jonas Geleyn as Chief Commercial Officer and given sport director Antoine Sibierski expanded ‘all‑in’ authority over all football operations, aiming for streamlined decision‑making. 2 sources. https://clstr.news/cluster/rsc-anderlecht-names-jonas-geleyn-cco-gives-sibierski-allin-authority --- Cite as: RSC Anderlecht leadership restructuring.
