Five Mexican footballers who were suspended from the Gold Cup for doping after testing positive for the banned substance clenbuterol were flown to Los Angeles on Friday for more tests. Mexico won 5-0 over Cuba on Thursday after opening last Sunday with a 5-0 rout of El Salvador, a result that could be protested in the wake of doping positives revealed Thursday from a May 21 test during Mexico’s training camp. Goalkeeper Guillermo Ochoa, defenders Francisco Rodriguez and Edgar Duenas and midfielders Antonio “Sinha” Naelson and Christian Bermudez tested positive for the banned muscle-building drug. Naelson, a Brazil-born playmaker whose flew home to his father’s funeral in Sao Paolo before joining Mexico for the Gold Cup, was angry about the positive test. “Right now, I am angry. The sadness comes later,” he told CONCACAF. “You are trying to get up after being knocked down and then you are hit and knocked down again. That is difficult and even more so knowing that you didn’t do anything. “I didn’t commit a crime or make any mistakes. My career will not be tainted for something I didn’t do. Everyone knows me.
