If you are lacking confidence to win when walking into a fight then your coach didn't properly prepare you. I would see a sports medical professional, if you haven't already, and have him access your old injuries. You don't want to further injure yourself and maybe there is something he can do for your knee, by taking away the unwanted irritation. Does it swell after training and do you have full movement in it? If you aren't healthy before a fight and you choose to do it anyway, you risk possibly never competing again. Almost everyone has some bumps and bruises from training hard, but a nagging injury can often become even worse. Your knee might not bother you much and a sports medicine professional might not be able to do much for you, but I believe in crossing all the T's and dotting all the i's, you want to put yourself in the best position to dominate your opponent.

I will be honest with you as a former pro fighter and champion if you have doubts which you do don't compete. This is one area where doubting one's self is unforgiving and must be overcome at all costs. Also before everyone takes a big shit on his coach he could be trying to protect him we don't know all of the details. Also brother what is your goals by competing if it is for the experience and you don't mind getting injured then go ahead. Is your coach good? Does he make champions if so you might want to listen to him. I am a trainer/teacher in many different areas people may think I am a negative bastard but I tell the truth as I know it. My job is to keep my guys safe not pump their ego up so that they get wiped out. If they have the goods I say it if they don't I say it.

I am all for fulfilling dreams and desires but a lot the time a bad choice will end those dreams and desires forever. You see young guys come here and want to get big over night. They know shit all about nutrition and believe 5 aas compounds at once will do it there first time out. When someone says that is stupid they come back with the sulking attitude of "you don't want me to succeed!" Which is bullshit, others who are wiser know that is not the way to long term success.

So again is your coach good at making champions. Does he have any personal reason to see you fail? If the answer to those questions is Yes he does make champions and No he has no reason to see me fail. Then listen to him and stop going everywhere until someone agrees with what you want to do! Good luck brother.
