I do not care about those stars, but only because that position is tweaked. Those stars are for a traditional Wide Midfielder, with the default settings. The same goes for all the other positions. All of them are tweaked, the Central Midfielder does not need to be a natural Central Midfielder, the Advanced Midfielder does not need to be a natural Advanced Midfielder, etc. Just look at their instructions and find out what fits best...oh wait, TFF has done that for you in the OP
I ask because I am using this tactic with a lower league team, with success also I might add. So yes, using the filters and finding a Mata or a Messi is an option but not when you are FC United of Manchester. As you probably know with lower league teams and promotion, Im going through players like its going out of fashion and as is atm, rely on star ratings to gauge their usefulness.
