Link above, I keep getting this message I just changed formation to train it during pre-season and iv'e got this message i'm sure it's some sort of error, I understand if i'm consistently drawing or losing games but my first season I came second in the league and won the Europa League & FA Cup finals and I was getting this message all season.
