Dušan Tadić is also set for international action (7.45pm BST), as Serbia lead the way in Group D. They will secure automatic qualification with a victory away to Austria tonight, or have the buffer of a home tie with Georgia on Monday to gain the necessary points.
Striker Shane Long is set to play at the Aviva Stadium (7.45pm BST), where the Republic of Ireland can keep their play-off hopes alive by defeating Moldova, ahead of a big home game against Wales.

Italy will be favourites for the win, having already secured at least a play-off place, but trail Spain by three points heading into the final two qualifiers.
