Hehe, play more games. Do you think you are more defensive when you play than when you play in the game? Moreover, you lack experience and confidence, and you will be nervous when you play the last game. Just play more games. Once you play with confidence (for example, you score several goals in a game), you will become more and more confident, and you will be able to play your usual level ... Also, opponents will not give you comfortable shooting angles and relaxed time in the game, so you must practice your basic skills hard at ordinary times. I wish you find your confidence on the field as soon as possible. -Captain of the varsity team
