Ange Postecoglou’s side will visit Barry Ferguson’s Wasps seeking a second piece of silverware having already got to grips with the Premier Sports League Cup last month.
Some 29 places separate the sides in the cinch SPFL league ladder with Alloa 8th in League One and Celtic four points off the summit of the Premiership.
That said, the artificial surface at the tightly packed Indodrill Stadium will pose it's own difficulties for the Premiership side in the final match of the round.
Of course as we have seen already there are no replays at this stage of the competition and any drawn matches proceed to extra-time and penalties, if required.
