Buchanan hasn’t played that much since joining Chiefs in June last year.
The midfielder is said to be looking for a deal away from the club due to lack of game time under coach Steve Komphela.
Buchanan recently posted a video of himself in Bloemfontein Celtic colours providing assists to his former teammates.
Celtic and Chiefs have done some business during the current January transfer window, with Kabelo Mahlasela joining Chiefs and Lorenzo Gordinho going the other way on loan. Therefore one cannot rule out the possibility of Buchanan’s return to Siwelele.
