The match between Iran and South Korea ended in a goalless stalemate.
“We faced a very strong team and I believe that overall, our players performed very, very well,” he said. “But it would have been better if there had been a goal.
“We dominated the game, had a bigger share of possession, made successful passes and created more scoring chances and we can deliver at a greater capacity if we work on our weaknesses.”
Iran will face the 2018 champion Uzbekistan on Saturday.
