Dan Crowley will have a medical at Willem II ahead of a permanent return to the Dutch Eredivisie.
Arsenal teen Crowley will sign a three-year deal as he searches for more regular football for a fee based heavily on his success.
The 19-year-old midfielder made a good impression in Holland during a six-month spell with Go Ahead Eagles despite relegation.
Arsene Wenger is a big admirer of Crowley's ability but with only a year left on his Arsenal contract he was determined to leave and develop his career.
