Battle for survival

Nigeria are keeping everyone guessing about their plans for the World Cup Group B match with Greece on Thursday, training in seclusion on the Indian Ocean coast since their defeat by Argentina.
Both sides desperately need points from the clash in Bloemfontein's Free State Stadium to keep alive their hopes of reaching the second round. The omens do not favour the Greeks.
Nigeria have largely kept their own counsel at their camp at Richards Bay north of Durban, founded as a British army base for their campaign against the Zulus in the 19th Century.
The Super Eagles could take some encouragement from Saturday's 1-0 defeat against an adventurous Argentina side in Johannesburg, a game lit up by Lionel Messi.
Nigeria goalkeeper Vincent Enyeama made a series of excellent saves, a stubborn defence helped keep the score down, and the attack caused the South Americans sporadic problems.
Fortunately, fullback Taye Taiwo recovered quickly after being taken off injured and resumed training on Sunday.
Nigeria's Swedish coach Lars Lagerback will have to decide whether to stick with Chinedu Obasi on the right side of the attack, after he started promisingly but tired quickly and was replaced by the experienced Peter Odemwingie on the hour.
For the Greeks, the fact is a side built on solid defence let its guard down in a 2-0 defeat by lively South Korea in Port Elizabeth on Saturday is a worry. Coach Otto Rehhagel has warned his players they cannot afford another lapse in concentration.
Greece have yet to score at a World Cup and failure to do so against Nigeria would leave them staring elimination in the face ahead of their last group game against Argentina.
Rehhagel is likely to make several changes, adding some muscle with center back Socratis Papastathopoulos and Sotiris Kyrgiakos, a rugged defender who can come forward to provide a bigger obstacle for the powerful Nigerians.
THE KNOWLEDGE
The four wins managed by Nigeria in the World Cup have been against European sides.
Greece have still failed to score a goal in the World Cup, conceding a total of 12 goals in their four finals games so far.
