Charlie Mulgrew and Corry Evans are both back on the World Cup trail this Monday night.
Mulgrew's Scotland take on Malta at Hampden, whilst Evans is with the Northern Ireland squad for their qualifier against the Czech Republic in Belfast.
Following the Scots' 3-0 win over Lithuania last Friday, they need to claim another three points to put pressure on second-placed Slovakia.
The Slovaks sit four points ahead of Scotland in the crucial play-off place, but with them facing group leaders England, Gordon Strachan's side have a great opportunity to close the gap further.
Northern Ireland's quest to reach next summer's finals in Russia is much more straightforward. They simply need to avoid defeat against group rivals Czech Republic to secure a second-placed finish.
The Northern Irish are seven points ahead of the Czechs and need just one point to finish second behind Germany.
