I think what he is more concerned about is not the rating but the performance. We all know ratings are almost as accurate as weather forecast, but in his case, it seems valid. GK is letting in goals and not performing as he did last season.

Well, this is normal for most players in T11. They will have a great season, then it runs full circle and they have their bad season. They will usually get over this but it will take maybe half a season. If they don't then they are a one hit wonder.
