The Belgian joins from Warri Wolves, where he failed to replicate the same success he enjoyed at Ocean Boys, Enyimba and Kaduna United.
Wolves, despite heavy investment, only avoided relegation on the final day of last season.
Gombe United team manager Ibrahim Kwairanga exclusively divulged to KickOffNigeria.com that Cooreman will replace Bernard Ogbe, who was axed at the end of the season.
"We have concluded plans with Cooreman and he has accepted to be our technical adviser for this coming season," Kwairana said. "We will unveil him next week."
