THE pressure is off when already-qualified Group I top two Russia and Belgium go head to head in St Petersburg.
Belgium have won all eight games so far, scoring 30 and conceding just one, while the Russians' sole defeat came in Brussels.
Eden Hazard and Co – the world's No.1 ranked team – won't give up their 100% record easily and Belgium can eke out the win at slight odds against.
In Belfast, Northern Ireland are likely to need to beat Group C rivals Holland to keep their automatic quantification hopes alive.
Michael O'Neill's men ran the Dutch close in Rotterdam, taking a 75th-minute lead before succumbing to a 3-1 defeat, and will again look to keep things tight early on.
It was scoreless after 45 minutes when Northern Ireland hosted Germany and another half-time stalemate this time looks a decent prospect.
Scotland's top-two hopes in Group I are long gone although they do have a Nations League play-off already secured when they head to Cyprus.
