How do you get your Keeper to save a shot? In the last 5 games i've played, my keeper has conceded 9 goals from 9 shots on target. This is in my opinion extremely unrealistic. In those five games, wouldn't my opposition have had a daisy cutter that he would have comfortably saved?

My keeper is 4* by coaches in Seria C1/B so it's not from lack of ability. Just can't understand, how this is even possible in real life. One of those games the AI had two shots in whole game and they both of course went in. Any tips at all before I give up on this game?
