"This will surely be a challenging game. The players don't have much time to prepare, but we will try to concentrate at the highest level. Japan's target is nothing but getting three points," Moriyasu said in the pre-match conference Wednesday.
Moriyasu is also impressed with the Vietnamese squad.
"Vietnam have been improving quickly recently. They are a quality and well-organized team. I'm really impressed with them. In Southeast Asia, Vietnam are really strong," he said.
To prepare for this game, Japan have brought their strongest squad to Vietnam, including players competing in top European leagues.
"We have hosted many meetings just to prepare different plans for this game. In the first four games, Japan haven't got the best results, but I think the players did a good job. What we did recently was to learn from the previous games, and at the same time train as hard as we can. The Japanese players who flew here from Europe have had a few days to rest after the Sunday games. I will assess the condition of each player and make the final decision tomorrow," Moriyasu said.
The Vietnam and Japan clash will be held at My Dinh National Stadium in Hanoi from 7 p.m. The game will be reported live on VnExpress International.
