LONDON — The World Anti-Doping Agency urged football Tuesday to conduct more blood doping tests and intelligence operations to unmask cheating players. Ahead of a meeting with FIFA President Sepp Blatter Thursday, WADA leaders expressed concerns that not enough is being done to discover if players are using blood-boosting EPO. "Football is not testing enough for EPO. They can do more and we are encourage them to do more," WADA President John Fahey said. Last week, Spain's anti-doping agency announced it was examining claims by a former president of Spanish team Real Sociedad that its players used performance-enhancing substances. Fahey questioned why the use of biological passports in football is so limited, with only FIFA starting to use them for players at its competitions in the last two years. Fahey also said that cycling faces a "crisis of confidence" over doping after the Lance Armstrong scandal. Fahey said he had received a letter from the UCI late Monday suggesting the creation of a new inquiry to include four UCI members but not the governing body's president, Pat McQuaid. In a separate interview WADA director general David Howman said that virtually all the raw materials used to produce illegal performance-enhancing drugs come from China. "Ninety-nine percent of the raw materials that are used through the Internet to make up in your kitchen or your backyard laboratory are emanating from China," Howman said in the interview with Reuters television during the WADA media symposium here. — Agencies
