Negotiations between Christian Burgess and Union had been ongoing for a long time. Initially, there was an intention to reach an agreement before the play-offs, but this did not happen, and new talks after the season also did not result in an agreement. According to reports, Christian Burgess requested a two-season contract, which Union was willing to consider. However, Burgess also wanted a guarantee that he could leave for free if an interesting offer was received, a point which Union was not willing to accept.

Christian Burgess's contract at Union SG has expired and he has decided to leave the club. Both parties announced via the official club channels that Burgess did not agree to a possible contract extension. It is currently unknown where Burgess will continue his career.

CEO Philippe Bormans told Het Nieuwsblad that, in relation to Christian Burgess's expiring contract, both parties know what they want and what is possible. Bormans also said that it is time to make a decision, and that although no deadline has been set, internal agreements have been made.

Christian Burgess would be available for a free transfer after the season, as he has not yet extended his expiring contract at Union SG. SudPresse reported that talks have already taken place with the management about an extension. During the match at Westerlo, supporters displayed a banner urging the club to extend its contract with the central defender.
