One thing should be certain; the Greeks cannot be as insipid as they were against South Korea. Given that their final match is against Argentina, they have no option but to attempt to go for the win. The trouble is that the 71-year-old Otto Rehhagel's tactics of defending deep and attempting to snatch something on the break or from a set-piece are so set in stone that it seems impossible to see how they can be altered. Certainly, after the disaster in Port Elizabeth, their striker, Georgios Samaras, said they would have to do better from corners,which they wasted against the Koreans.

Given the importance of this fixture, manager Lars Lagerback may be tempted to start with Obafemi Martins, who caused the Argentine defence problems at Ellis Park. Defensively, they have the player of the week in goalkeeper, Vincent Enyeama, who is unlikely to be as troubled by the Greece attack as he was by Lionel Messi. Their one injury concern is over Taye Taiwo, who pulled a hamstring against Argentina, but who should be fit to face Samaras and Co.

Both sides need to win or prepare to go home and, on balance, Nigeria look far more equipped to drive for victory than Greece. They will not need to radically alter their tactics, although the danger must be that they attack in a wild, uncontrolled manner and leave themselves vulnerable to Greek counters. Verdict: Nigeria to win.
