Czech Republic vs. Italy - 7:45 pm BST, 2:45 pm ET
Italy are on top of Group B with a three-point lead over Bulgaria, and the Czech Republic have a two-point deficit to catch up if they want to secure second place. A win for the Czechs here could make the top of this group very interesting indeed, and this should be a tricky away test for Italy. Victory for the Italians will be a huge step on the road to qualification.
Germany have an eight-point lead at the top of Group C with Austria, Sweden and the Republic of Ireland all tied on eight points in the three places beneath. Even though Austria and Ireland have two games in hand and the Swedes have one, it's hard to see the Germans giving up first place here, so there's an intriguing battle for second taking place. Sweden have an extra game, but defeat here would leave them in real trouble, while Ireland will be hoping for a draw.
Albania vs. Norway - 7:30 p.m. BST, 2:30 p.m. ET
The very weak Group E has resulted in the likes of Iceland and Norway competing at the top of the group, and this is a surprisingly important game. Norway are in serious trouble, and a defeat would be a terrible blow to their hopes of second place. Albania will need a win to keep in touch with group-leaders Switzerland and Iceland, who face bottom-placed Slovenia.
Portugal vs. Russia - 8:45 p.m. BST, 3:45 p.m. ET
Russia may only be on top of their group by one point, but they have a perfect record. They have won all four of their games so far, and thus have two games in hand on Portugal and Israel, who are both on eleven points. That leaves Portugal in danger unless they can start finding some form. They need to get a result at home and end Russia's perfect record.
Montenegro surprisingly lead Group H after some dismal displays by England, and if they can defeat the underachieving Ukraine then they can move five points clear in the top spot. Ukraine have a game in hand on both, and realistically need a win to keep up their hopes of qualification.
