As of my last knowledge update in January 2022, I don’t have specific information on Hérita Ilunga’s current situation or whether he successfully joined En Avant Guingamp. The information you provided suggests that he was on trial with the club and that the decision would be made after a match against Istres.
For the latest and most accurate information on Hérita Ilunga’s career status and whether he secured a place at En Avant Guingamp, I recommend checking recent sports news, the official website of En Avant Guingamp, or other reputable sports journalism sources. They would provide updates on trial outcomes and any subsequent decisions regarding his potential signing with the club.
