I would actually say that's good! Whether I win massively, by a small margin, draw, lose, my goalie gets rated 5 every single match! I'm on Level 4 and he's 5* rated 35. I had a similiar issue last season with a goalie who at Level 3 was 5* rated 32 and he just kept scoring 5's as well, so sold him, went and bought a slightly better and younger goalie and the same thing keeps happening! Just to wind me up, everytime I play my reserve goalie who only has a rating of 17, he scored 7 or 8. Stupid goalie stats......
