Mario Stroeykens is being linked with a move from RSC Anderlecht to Turkish side Beşiktaş, according to transfer data compiled on 16 December 2025.
The 21-year-old attacking midfielder is the subject of speculation over a possible switch from the Jupiler Pro League to the Süper Lig, with the move currently listed with an unspecified probability. Transfermarkt data places his market value at €8.00m at the time the rumour surfaced, a figure that is likely to frame any negotiations between the Belgian club and the Istanbul giants.
Stroeykens’ contractual situation at Anderlecht is unclear in the published data, with no expiry date recorded, leaving open the possibility that he could move on under different conditions, including potentially as a free agent further down the line. For now, however, the link to Beşiktaş remains in the realm of rumour rather than an agreed deal.
Born in Zellik on 29 September 2004, Stroeykens has progressed entirely through Anderlecht’s system, moving from the club’s youth ranks to RSCA Futures before stepping up to the first team in 2021. Standing at 1.77m and preferring his right foot, he is listed primarily as an attacking midfielder but broadly categorised as a midfield player.
His market value has fluctuated notably in recent seasons. From €500,000 as a 16-year-old in early 2021, it climbed to a peak of €14m in December 2024 before easing back to €8m by December 2025. That downward adjustment may encourage interested clubs who see an opportunity to sign a player regarded as one of Anderlecht’s more valuable assets.
Eligible for both DR Congo and Belgium, Stroeykens would be adding a new league to a career so far confined to Belgian football should a move to Istanbul materialise. If Beşiktaş do firm up their interest, the transfer could mark a decisive next step in his development and determine whether he becomes a long-term prospect on the European stage.
