Celta de Vigo's option to sign Abdul Mumin was not completed a few weeks ago because the 28-year-old Ghanaian centre-back did not pass his medical examination. Mumin was present at the club's Cidade Deportiva Afouteza facilities for the examination. The former Rayo Vallecano defender, who was without a club after a serious knee injury in 2025, has since received medical approval from Girona and signed for the Catalan team on Monday. Mumin has 5 caps for Ghana, and his current market value is €3.00m, according to Transfermarkt.
