"The two equalizers from Iran are both from freekicks. We need to improve our ability on the defense against freekicks before the next match," Zhu said after China were held 2-2 draw with Iran in a hard- fought match at Asian Cup.

"We play very well in the first half and scored twice, which greatly limited the performance of Iran. It is a pity the match ended in a draw," he said.

The players should do better in the second half, and China must solve some problems before the next match against Uzbekistan.
