FC Porto is monitoring the situation of 20-year-old Belgian midfielder Mario Stroeykens, whose future is unclear after a potential transfer failed to materialise last summer. The player is in talks with Anderlecht about a contract extension, but several clubs are reportedly interested in a January move. According to Jeunes Footeux, Olympique Lyon and Olympique Marseille are considering an attempt to bring the midfielder to Ligue 1. While Anderlecht hopes to retain Stroeykens until the end of the season with a new contract, a transfer could proceed in January if a multi-million euro bid arrives. AC Milan is also keeping an eye on the file, and Sporting Braga remains an interested party, having previously seen a €6.5 million offer rejected in the summer. The player's market value is estimated by Transfermarkt to be €12 million.
