Japan boss Alberto Zaccheroni was delighted to see his players return to form in the past five days.
The Blue Samurai were beaten 4-2 by Uruguay last month but put that result behind them by cruising to a 3-0 victory over Guatemala in the first of their two Kirin Cup Challenges on Friday.
“I told my players that I was satisfied with their performance,” Zaccheroni told reporters.
“They played aggressively while keeping the midfield tight and pressured their opponents well.
“I was able to see that in the Guatemala game, but today it was clearer. We played much better today, especially against our tough opponents. We dominated in midfield and created good finishing opportunities and made more attempts than our opponents.
“On top of that, our players responded well after giving away a goal. They made a good recovery to fight back in the game. Every player has a different role but all of them did a good job today.”
