Official confirmation of the deal has been put on hold until a work permit is granted but AllNigeriaSoccer.com report that NEC hope it will be sorted this week.
“Nothing is delaying Awoniyi's move to NEC Nijmegen, all is sealed and settled," a source told the website.
“The rule in Holland is a little different. Until the work permit is granted, NEC can't make the transfer official but we hope it is granted this week."
Last season he was loaned to German side FSV Frankfurt where he scored one goal in 14 appearances.
