As of the end of May, China's national team has won only one game out of their three matches against Qatar. The issue that needs attention is the defensive coordination between the defense and midfield.
The Chinese team has been known for its strong defensive style, but in this match, they were unable to create enough pressure on the opponent's goal. This was due to the lack of communication between the defense and midfield, as well as the absence of adequate support from the attacking players.
One reason for this is the lack of clear lines of communication between the defense and midfield. The midfield had difficulty communicating effectively with the backline, which made it difficult for them to anticipate the direction of the ball and create opportunities for goals. Additionally, the defense struggled to get the ball down into the box, making it difficult for the goalkeeper to maintain control over the ball.
Another factor contributing to the poor performance of the defense was the lack of adequate support from the attacking players. The team lacked the quality of players who could provide counter-attacks or assist in creating chances for goals. This meant that the team had to rely more on their own skills rather than relying on the attacking play of the midfield and backline.
Overall, the defensive coordination between the defense and midfield was a major weakness for the Chinese team in this match. It will be essential for them to address this issue if they want to improve their overall performance going forward.
