Central Coast Mariners will not be able to sign Youssouf Hersi during the A-League transfer window due to an 11th-hour mix-up with the 33 year-old's visa.
Hersi, who had already passed a rigorous medical test, was on the verge of signing with the Mariners until at least the end of this A-League season, with a view to being available for Saturday's away clash with Brisbane Roar.
But with only hours remaining before the close of the January transfer window on Tuesday night, Mariners' club officials found out that Hersi had travelled to Australia from the Netherlands on a tourist visa instead of a work visa.
Hersi's failed recruitment is a blow for the Mariners, particularly as it had already been a drawn-out affair, after his original arrival date weeks ago had been delayed due to a mix-up over the validity of the Dutchman's passport.
But after the 33 year-old finally arrived in Gosford last week, he had since undergone medical and fitness tests, and trained with the Mariners on Tuesday morning.
