The home team come into this on the back of a disappointing goalless draw at home to Atromitos last weekend. That draw means that Olympiakos have now drawn three successive matches in all competitions. The hosts have lost just one game all season and that was in their UEFA Champions League third qualifying round second-leg against Ludogorets Razgrad.
They come up against a Royal Antwerp side that defeated Eupen away from home at the weekend to extend their own unbeaten run of form to three matches after their penalty shootout victory over Omonia Nicosia in the playoffs of this competition.

Pedro Martins's Olympiacos have found the net a sum total of nine times over their past half-dozen outings. The tally of goals that have been scored against them in that same time stands at five.
