The Asian champions are expected to depart the World Cup at the group stage following two poor showings and their Italian coach has lamented his team's mentality
With Japan on the brink of group stage elimination from the World Cup, coach Alberto Zaccheroni has lamented his side's weak mentality.
A failure to beat Colombia will see the Samurai Blue knocked out at the group stage, while they will also need Greece to take points off Cote d'Ivoire to have any hope of progressing.
"The problem is probably mental," Zaccheroni said. "We're not satisfied with our performances so far. This team has given lots of joy and satisfaction in previous matches over the past four years, so I'm hoping we can show that good part of our football against Colombia."
The Japanese take on Colombia on Tuesday in the sweltering conditions of Cuiaba after losing their opening game to Cote d'Ivoire and following that disappointing result up with a 0-0 draw against Greece.
They failed to capitalise on their one-goal lead against the west Africans and could not break down a Greek side who were down to 10 men. And Zaccheroni feels the team is not playing to the same levels which have brought continental success.
"We haven't had enough speed in our play and it's as though the players have been playing with the brakes on," he added.
