Anxiety.

I am playing U15 soccer and our club is split into 3 teams. A Team, B Team, C Team. I am on the B Team. However, I am playing the A Team in indoor soccer(because it’s winter) today. I am nervous because they are the same age, but significantly better. I am hoping to try out for them in the summer but I am nervous because their coach is watching and I am anxious if I will do bad and he would not have interest in me pre tryouts, leading him to look at other guys. How do I deal with this? Is anyone experiencing the same?
