Manchester United midfielder Shinji Kagawa believes that they put on a miserable show in their 2-1 loss to Mexico in their final game of the Confederations Cup.
The Samurai Blue would have been hoping to follow on from their impressive performance in their 4-3 loss to Italy but instead were second best to the Mexicans for most of their game.
"We played fuzzily; even when we attacked, [Okazaki] was the only one giving his all and it feels like ... what on earth did we come here to do?" he told reporters. "It was a miserable performance.
"We didn't have anything left and lost in a very Japanese fashion. We tried hard but we lost.
"We had some good chances in our build-up and it felt like both teams were drifting a bit so, if we'd been able to score first ... we weren't able to score in those situations in all three matches, so it's a problem we have to consider," he added.
"At minimum, to beat a team like Brazil we have to improve individually and as a team, and we saw again that if we don't fight as a team we can't win; in the second-half it felt like Mexico wanted to win more."
