A potential January transfer for Michel Ange Balikwisha is complicated by his European registration status, as rules prevent him from playing for a third European club this season. The 24-year-old winger joined Celtic from Royal Antwerp six months ago for a reported £5 million but has not played for the team since early December. A return to Antwerp is one possibility for him to continue playing in Europe, though it is not certain if Celtic would agree to such a transfer.
