Japan manager Alberto Zaccheroni urged his players to hone their touch in front of goal against Ghana on Tuesday — or risk being embarrassed by another of the world's top teams.

The Asian champions coasted past Guatemala 3-0 on Friday in Osaka, but Zaccheroni on Monday said he was not pleased with his team's lack of accuracy against a Central American side already out of the picture for next year's World Cup.

Zaccheroni said should Japan fail to make the most of their opportunities against Ghana, who reached the quarterfinals at the 2010 World Cup and are on course to qualify for Brazil, they will be pay the price.
