Even though Greece were underdogs coming into this game, that is a tag they have enjoyed for a long time and there was always the risk of them surprising Croatia in this fixture.
The Croatians gave Greece no space in the first leg with the Greeks ending 4-1 losers and now have a mammoth task at hand as they host the Croatians at the Olympiakos stadium.
The Greeks were lacklustre in attack in the first leg of this game and it is hard to see them overturn this result here.
Croatia will still be hurting by their inability to qualify automatically ahead of Iceland and what led mainly to that disappointment was their away form.
They have won just twice in their last seven visits in all competitions and scored only six goals in those matches.
Playing a defensively organised side like Greece away will reduce their chance of scoring in this game and if the Greeks can stop them from the early onslaught which helped them gain an edge in the first leg, they could see their game plan frustrated early on.
Croatia are expected to start the game defensively on Sunday and although they are favourites with bookmakers to win this fixture, they will happily settle for a low-scoring draw that will ensure their place in Russia next summer.
