I hear ya, I used to play like that too when I had 3 star players, but I realized that I needed a stronger squad, so I started selling 3 stars and keeping only 4 and 5 stars. Right now I have 3 GK, 2 of them are 78 quality (5 star for me) and are OS, but they are 29 and 31,and I have a 72 quality 21 year old, so I play my 29 and 21 year old and let my 31 year old sit on the bench until one or both of them gets injured or out of form.
