Nigeria midfielder Sani Kaita has been inundated with death threats from home after he was sent off in the Super Eagles' 2-1 loss to Greece in their Group B World Cup match Thursday. “Kaita has so far received more than 1,000 threats to his email from within Nigeria,” said team spokesman Peterside Idah. “We are taking these threats very seriously. We've spoken to the Nigerian government to inform them about it and also written to FIFA to notify them,” Idah told Reuters by phone from Nigeria's base some 200 km north of Durban. Nigeria was leading 1-0 in last Thursday's game when Kaita kicked out at Greece's Vassillis Torosidis on the touchline in the 33rd minute. The referee showed him a straight red card. The west African side went on to concede two goals, seriously damaging their chances of getting to the second round of the tournament in South Africa. “We consider it a very serious matter because this is a young man who is putting his best at the service of his country and football,” Idah said. “That is why the team received the news of the threat to his life with shock and disappointment and is urging the authorities in Nigeria to take measures to protect him.” He said the 24-year-old midfielder was “terribly shaken, but, fortunately, he is receiving great support from his teammates and team officials”. Nigeria takes on South Korea at the Moses Mabhida stadium in Durban Tuesday and must win to stand any chance of qualifying. The team spokesman said defenders Taye Taiwo and Elderson Echiejile, who suffered injuries in the match against Greece, were making “good recovery” and might be available for their final group game. Kaita had apologized “to everyone” Thursday. “I apologize to everyone. To the Nigerian people, the officials and my teammates,” he told reporters after his first-half sending off for violent conduct. He left the pitch with his shirt pulled over his head. “I accept the red card as a justified decision, I am very disappointed, I hope Argentina can help us out,” Kaita glumly added after missing out on the rest of an entertaining match. Victory for Greece puts it on three points with South Korea, who was trounced 4-1 by table-topping Argentina earlier Thursday, while Nigeria has no points from two games. Nigeria, one of Africa's great hopes for the competition, must now beat South Korea on June 22 in Durban and hope that Argentina can beat Greece in Polokwane the same day to have a hope of progressing. Laid-back forward Nwankwo Kanu remained typically relaxed about his country's chances. “If you look at the table it is not really bad, but we need a win,” he told reporters. “We cannot go for a draw, we have to go all out and make sure that we win and then it depends on what happens between Argentina and Greece.”
