Argentina Wednesday failed to make up for its disappointing opening draw against Bolivia when it could only manage another stalemate against Colombia, compromising its bid to reach the Copa America quarterfinals. Once again, despite on paper having an embarrassment of riches in an attack spearheaded by Lionel Messi and Carlos Tevez the albiceleste managed to flunk what was its first-ever competitive international in the northeastern city of Santa Fe. “They were tough opponents, they knew how to mark us,” said Tevez afterwards. “Things are not going for us right now the way we want them to,” said Argentina coach Sergio Batista, who replaced Diego Maradona after last summer's World Cup. Two test positive Football's governing body FIFA banned North Korean defenders Song Jong-sun and Jong Pok-sim Thursday after they failed a doping test. “Two players from Korea DPR, Jong Sun Song and Sim Pok Jong, were provisionally suspended prior to their team's match against Colombia in Bochum yesterday in view of adverse analytical findings in the ‘A' samples collected during two anti-doping tests conducted after the team's previous matches in the 2011 FIFA Women's World Cup,” said FIFA in a statement. The pair were removed from the lineup for North Korea's goalless draw with Colombia in Bochum Wednesday, but after the Group C game, the entire team was tested by FIFA.
