I've always said to anyone that has a keeper that keeps getting poor ratings... is how easy are you winning games? If yes, then your keeper is being reduced to a spectator on a regular basis and has nothing to do all game, so the NGE thinks the keeper had a bad game!
It's quite simple, if a keeper keeps a clean sheet, give him a minimum of a 7/8 rating.
But as usual, Nordeus employs an idiot of a game designer.
