Africa's 2010 World Cup teams have been criticised for a lack of preparation and professionalism by Amos Adamu of the Caf Executive Committee, reports BBC Sport. Algeria, Cameroon, and Nigeria opened with defeats while hosts South Africa drew with Mexico.

Ghana was the only African team to win their opening group game.

"Everybody thinks we have good players in Europe, and don't need to prepare," Adamu told the BBC's African sport programme Fast Track.

"But it's not the same thing playing for the national team where you have to blend players from different places."

South Africa became the first African nation to be awarded the World Cup in 2004 but Adamu has suggested that the teams did not take advantage of the notice period.

"Even if you give us 10 years to prepare, it will be the same because up till now many of these countries don't recognise professionalism in their preparations," he added.

"One of the problems we must get right here in Africa is that we need to plan ahead.

"Because if you don't plan ahead, you're planning to fail. Nigerian Adamu had particularly harsh words for the Super Eagles who only appointed Swede Lars Lagerback at the end of February.

"The teams are so haphazardly put together," Adamu stated.

"With some countries like Nigeria, the coach does not know the players.

"He just met the players less than four weeks before the World Cup and the players are on their own."
