Going into the last group stage game, a lot of teams are hanging by the thread as their respective games are arguably "do-or-die". Here are some key fixtures that would determine the fate of these nations!

1) Argentina vs Poland

Cristiano Ronaldo is through in Group H, but can Lionel Messi follow suit in Group C? Argentina are set to take on Robert Lewandowski's Poland in their final group game and a win would seal their participation in the next round! Can Messi do it once again?

2) Croatia vs Belgium

This European banger will indicate who goes through from Group F. This is a must win game for Belgium as they are currently third in their group. If Morocco beat Canada, the Croatia vs Belgium game would be a virtual knockout!

3) Costa Rica vs Germany

Germany have just 1 point in 2 group games. Their final game would be against a Costa Rica side that are riding high after a win against Japan. A win would put the Germans on 4 points, but still their qualification could depend on the result of the Japan vs Spain game in Group E.

Other Key Games:

Group A: Ecuador vs Senegal (Winner goes through)

Group B: England vs Wales, USA vs Iran (Group is wide open)

Group C: Denmark vs Australia (A Denmark win could send them through)

Group D:  Saudi Arabia vs Mexico (A Saudi win guarantees qualification for them)

Group G: Serbia vs Switzerland (Winner would qualify depending on Cameroon vs Brazil's result)

Group H: Uruguay vs Ghana (Winner qualifies)
