Feyenoord is interested in the Spanish defender Mika Mármol, particularly due to the potential departure of Tsuyoshi Watanabe. The 29-year-old Japanese player seems open to a transfer this summer, as reported by Voetbal International. Feyenoord sees Mármol as a valuable addition since he can be signed for free from Las Palmas, where his contract is expiring. Several clubs are showing interest, but Feyenoord has a significant advantage with the Champions League. Club watcher Martijn Krabbendam mentioned in the Dick Voormekaar Podcast Extra that Mármol was already on Feyenoord's radar last year, but it was difficult due to rights issues. Now, the club offers the chance to play Champions League football, which could be appealing to the player. Mármol's potential arrival is also a response to changes in the squad. Watanabe is now 29, and if he wants to take the next step, this is the time. Feyenoord needs to look ahead, especially regarding the situation with Trauner. Watanabe joined last year for around eight million euros from KAA Gent, and his contract at De Kuip runs until mid-2029.
