World Cup betting has been brisk in the United States, according to BetUS spokesman Reed Richards.
"The World Cup has exhibited some really heart stopping action — particularly in the case of the U.S. squad," Richards said. "It was apparent that this World Cup showing was a big one for the sport of soccer in the U.S. before the tournament started, but has been backed up by the amount of interest people have shown in our site long before and even more so since the tournament has begun."
ETO'O READY FOR MORE: Cameroon striker Samuel Eto'o pledges to continue playing for the west African nation despite its poor performance at the World Cup. The striker scored twice in Cameroon's three group defeats in South Africa. Early elimination was a massive disappointment for a player so prominent in promotional material for the first World Cup in Africa. "There's no point blaming one person or another," he said. "We have to focus on the future, and we don't have much time to build it."
NOT ENOUGH BANG FOR THE BUCK: South Africa failed to justify the money pumped into the team with its opening-round exit from the first World Cup to be held in Africa, former national coach Jomo Sono said. "I strongly believe we could have done better with the preparations we put in, with the money we put in, with a highly qualified coach as well. For any tournament … the host country must not go out too early because it can affect the competition."
