Ok, I'll give you simple things to do. They are so simple you'll probably think they don't work. And because you think they won't work, you'll probably won't do them. And becuause you won't do them, you'll have another bad game, and probably make another thread asking the same thing, in another way. And my friend, if you do, I'll be there and say, I told you so.
Anyway, rant out of the way.
You need two things: A Wall and a ball. Actually, you need two more things, patience and time.
1. Pick one or two but a maximum of three of the following drills.
2. Spend 5 out of 7 days a week for at least an hour, doing the same drills over and over again. If you get bored, stop. You must have your full attention every single pass and control.
3. Go on youtube, get an instep drive tutorial. Go for a popular one or one that seems decent to you. Analyse every nuance, and point. Pay attention. And go outside and see what it fels like for you. Try out how they do it first, and see how you can make it more comfortable for you. Spend an hour on each point. I recommend doing it before passing and control.
4. On game days, implement most if not all of these techniques:
Get on with your team mates. Be talkative. Talk to your coach. Ask him his plans. Ask him where he would like you to play. Get in a dialogue. Get inside his head, you'll know what pleases him, displeases him and you will act accordingly to that information.
What's the purpose of all these things?
I have identified 3 most pressing issues you have. Your touch, your shooting and your confidence. I've given you a plan. Go implement it.
