There are more explanations for this. First of all watching is never a way to win. It only gives you a few more percent ball possession. That is it. Ball possession doesn't say a thing. You could have the ball 75% of the time and still loose 3-0.

If you are not scoring goals then your team is either poor in quality, players are out of form or you are facing much stronger advisaries. Try to switch players, try to switch order (blue and red arrows), etc....
