BLOEMFONTEIN (South Africa) (AFP) Greece beat ten-man Nigeria 2-1 in a thrilling encounter on Thursday to record their first ever victory at a World Cup finals. It also kept their World Cup dreams alive in a match that hinged on a first half red card for the African team. The Euro 2004 champions - who had lost all three matches in the 1994 finals and then to South Korea in their opening group match here - knew that defeat would end their hopes in South Africa and fell behind early on. But goals from Dimitrios Salpingidis and Vasileios Torosidis sealed the win in chilly Bloemfontein. Nigeria broke the deadlock on 16 minutes through midfielder Kalu Uche, who swung in a free-kick from near the left corner of the penalty area that eluded everyone and crept in past a bemused Alexandros Tzorvas. But the Super Eagles hopes took a major hit when Sani Kaita was sent off on 33 minutes after kicking out at Torosidis, the Nigerian leaving the pitch in tears. As half-time approached Greece coach Otto Rehhagel threw on forward Georgios Samaras for defensive midfielder Sokratis Papastathopoulos as the Greeks, renowned for their defensive-minded play, seized the initiative. The pressure paid off when Salpingidis netted Greeces first ever goal in a World Cup finals after his shot deflected into the net off Nigerias Lukman Haruna to make it 1-1 at half-time. Nigeria took off Peter Odemwingie for Chinedu Ogbuke Obasi at the beginning of the second half, which started in lively fashion with both sides threatening. With less than 10 minutes gone in the second period the Africa side were forced into another substution when Uwa Echiejile replaced the injured Taye Taiwo. As the second half wore on the game became stretched and in a dramatic spell Theofanis Gekas was denied by Nigerian goalkeeper Vincent Enyeama before Nigeria raced upfield with Yakubu Ayegbeni forcing Tzorvas into a smart save and Obasi missing a clear follow-up chance. But minutes after pulling off a wonderful save Enyeama spilt a powerful shot by Alexandros Tziolis and Torosidis smashed in the rebound from close range, sealing the win. Despite the defeat the Super Eagles retain a mathematical chance of reaching the knockout stages. Argentina beat South Korea 4-1 in Johannesburg in the earlier Group B match. We lost a fight, still in the battle, say Cameroon Cameroon warned on Thursday that they might have lost a fight against Japan, but they remain committed to the battle that is the World Cup. The Cameroonians, in a record sixth World Cup appearance for an African country, went down 1-0 to the Japanese in their opening Group E game and on Saturday take on Denmark, who went down 2-0 to the Netherlands. But Monaco defender Nicolas Nkoulou was adamant that Cameroon could bounce back from that shock win for the Blue Samurai, their first World Cup victory on foreign soil. We lost a battle but not the war. Everyones behind us. Its important to react on the pitch, Nkoulou said. Were not very happy with the number of goals weve conceded (eight in the last three games). Well do all we can to perform better come Saturday. Valenciennes defender Gaetan Bong insisted there were some positives to come from the defeat to Japan, despite the team looking impotent in attack against a side that was considered by far the weakest in the group. Added to that problem was coach Paul Le Guens controversial decision to start captain and star striker Samuel Etoo on the right. It spectacularly backfired as Etoo had no service and was largely anonymous. There were some good things in the Japan game, Bong said. We tried to create some chances, and well look to the positives to take on for Saturdays match. The defeat was frustrating. We wanted to really kick off the World Cup with a win. Unfortunately that wasnt possible. Now we want to win and go far to disprove our bad start to this tournament. He added: Football is never perfect and its not only about winning. Were not the first team to lose a match. There were good things to work on, well put the bad things to one side and well move on and play a good World Cup. Real Betis striker Achille Emana moved to play down talk of any rift in the Cameroon camp. With Etoo unusually watching on from the sidelines of the press conference, Emana said: There are no problems in the camp. I have no problem with Samuel. Were all walking on the same path. The World Cup represents something very important for us and the country. We all want to win the match on Saturday. Both Cameroon and Denmark know that a defeat at the Loftus Versfeld stadium on Saturday could spell the end of their interest in this years tournament. If the Netherlands and Japan were to draw in the other group game, then a defeat would see either Cameroon or Denmark eliminated. But with two rivals already on three points, anything other than a victory will leave either side still with a mountain to climb in order to reach the knock-out phase.
