Having got off to the best possible start, Scotland (Group B), the Czech Republic (Group D) and Sweden (Group F) can all further their UEFA EURO 2008 qualification prospects by picking up their fourth straight victories this Wednesday.
They are not the only sides still with 100 per cent records, however, as Greece, Turkey (both Group C) and Germany (Group D) are yet to drop points after sealing wins in their only two games so far.
In Group A, Serbia will be aiming to extend their lead at the top of the standings at home to Armenia, buoyed by having overcome Belgium 1-0 on Saturday. Two points further back, closest rivals Finland sit the evening out and could also see themselves lose second spot when third and fourth meet in Chorzow for the highest-profile encounter in the section.
Favourites Portugal will be the visitors as Leo Beenhakker's Poland set out to register their first win at home, while in the other match Belgium host bottom-side Azerbaijan knowing they can no longer afford any slip-ups.
After failing to earn a place at the 2006 FIFA World Cup Germany™, Scotland are currently flying high at the Group B summit and enjoying a reputation as the real surprise-package of the qualifiers. Their courageous 1-0 victory over France at the weekend subjected Raymond Domenech to a first-ever loss as coach of Les Bleus in a competitive game and illustrated how far the Scots have progressed under Walter Smith.
Their next test ought to be just as stiff, though, with a trip to Ukraine on the cards and deadly striker Andriy Shevchenko expected to mark his return from injury for Oleg Blokhin's men. Elsewhere, the French have an excellent opportunity to get their own bid back on track against the Faroe Islands, who have shipped 13 goals in three games, while Italy will be hoping to build on their first victory under Roberto Donadoni by showing more than a few glimpses of their summer form away to Georgia.
Top of Group C on Saturday morning, Norway now find themselves lingering in third place and with no game scheduled for Wednesday, could slip even further back before the week is out. Indeed, fresh from seeing off Hungary 1-0 in their previous encounter, Turkey will be confident they can race to a third win in three matches against Moldova. Likewise, European champions Greece can do the same in Zenica, although their clash with Bosnia-Herzegovina will be anything but straightforward.
Having been spared a competitive fixture on Saturday, Group D powerhouses Germany should be in peak condition for their journey to Bratislava, where they take on a Slovakia team in impressive form. Dusan Galis' charges enjoy nothing more than streaming forward and have plundered 11 goals in two games, including five away to Wales on Saturday.
They are prone to leaving gaps in defence, though, as Karel Bruckner's Czech Republic proved with a 3-0 away win earlier in the campaign. For their part, the Czechs now travel to Dublin unsure what to expect from an Ireland side capable of an excellent performance one day - such as their slender 1-0 loss in Germany - and a dismal display the next, as illustrated by the 5-2 defeat suffered in Cyprus at the weekend.
England looking for goals
Criticised following his side's goalless stalemate at home to Macedonia, England coach Steve McClaren will be expecting a fierce reaction from his players away to Croatia, who warmed up for the tie with a morale-boosting 7-0 result at Andorra's expense.
Despite Wayne Rooney's return to the starting line-up, the English failed to turn their domination into goals on Saturday and must now make do without suspended midfielder Steven Gerrard in Zagreb after the Liverpool man picked up one yellow card too many.
With Israel not in action, a win would take Croatia top of Group E on goal difference, having contested one match less than their opponents. Meanwhile, Russia will be determined to erase memories of disappointing draws in their opening two fixtures with a first win when they lock horns with Estonia.
In Group F, the pressure is starting to pile up on Luis Aragones after Spain's 2-0 reverse in Sweden. His team boast just three points from three games and will be looking to set a few things right when they confront Argentina in a friendly, which means Sweden can put even more distance between themselves and the Iberians with maximum points from their trip to Iceland.
In the group's other encounters, Denmark will be expecting to win in Liechtenstein while Northern Ireland entertain Latvia. The worst possible collection of results for Spain in those matches would see them fall nine (Sweden) and four points (Denmark, Northern Ireland) adrift of their rivals.
Finally, having survived their Bulgarian excursion (1-1) and with Romania not playing, the Netherlands ought to re-establish their Group G lead when Albania come calling. At the same time, Bulgaria and Slovenia will be expected to bolster their own claims on one of the top two spots when they travel to Luxembourg and Belarus respectively.
