Both nations have suffered back-to-back defeats to France and Portugal, realistically leaving them to focus their attention on avoiding relegation.
When Croatia and Sweden were drawn alongside France and Portugal in Group A3, they would have accepted that finishing ahead of those two sides was highly unlikely.
Nevertheless, they will be bitterly disappointed having played a third of the group without getting a point on the board, effectively leaving them to battle for the minor positions at this stage.
In Croatia's case, they will feel that their two toughest fixtures are out of the way having already travelled to Lisbon and Paris during September.
However, conceding eight goals in that double-header will concern Zlatko Dalic, particularly when all of those strikes came after the opening 40 minutes.
Playing back-to-back fixtures in Zagreb provides Croatia with the ideal setting to turn things around as they bid to remain as outsiders for top spot heading into the last two games.
Meanwhile, Sweden have already played two of their three games in Stockholm, failing to get on the scoresheet in either of those encounters.
Like his Croatian counterpart, Janne Andersson will be contemplating what could have been with the Scandinavian outfit having also not conceded any goals until just before the half-time whistle.
Such developments have undermined their overall performances, and both managers will stress to their players that they can ill-afford any more lapses in concentration.
These two nations are squaring off for the first time since 2012 when Sweden recorded a 3-1 victory over Croatia in preparation for the European Championships.

While Dalic played a relatively strongly side against Switzerland in midweek, the Croatia boss is still likely to make several changes.
Mario Pasalic will also hope to be named in the first XI after getting on the scoresheet in Thursday's friendly.
Andersson is likely to take a similar approach when naming his Sweden team with Alexander Isak one of several players who will avoid dropping down to the substitutes' bench.
Croatia possible starting lineup:
Livakovic; Jedvaj, Lovren, Vida, Barisic; Brozovic, Modric; Brekalo, Pasalic, Perisic; Petkovic
Sweden possible starting lineup:
Olsen; Lustig, Jansson, Lindelof, Augustinsson; Forsberg, Olsson, Ekdal, Kulusevski; Berg, Isak
We say: Croatia 1-1 Sweden
Given their desire to avoid defeat on Sunday evening, we are expecting a relatively low-key affair. Croatia will likely make most of the running, but we fancy Isak and co to produce a moment of quality which secures a share of the spoils for their nation.
