they have a database of already given rates for players and just eventually see if they scored a goal or conceded 3 before changing them. I'm fairly sure Liverpool players would easily beat ours last season if all rounds would be summed up, despite us winning the league. VVD probably has in average at least 1 point better than Laporte, despite Laporte being main man in defence that conceded 1 goal more than VVD's. VVD is probably better between them, but it's ridiculous how are they they rate players out off their arse.
