Low ratings.

Hi, my keeper almost always have bad rating, what can be the problem? His ability is 90 with is a scout/6 star player at my level and his moral is superb. He has almost always fewer saved then the opponent goalkeeper, with means I often lose matches where I have more chances. He's the only spanish player on the team, could this mean anything?
His form is:
League: 4-5-6-4-5
CL: 5-4-5-5-5

Is there anything I can do, so he doesen't play a bad game almost every time??

PS. sorry for my English, it's not my native language.

Im afraid I think it's more to with a fault in the game rather than anything your doing.

GK's ratings make no sense in this game. Last season I lost a game 4-0 but my GK got a rating of 8 despite losing 4 goals and only making 1 save. In the next game I won 3-0 and my GK got a 5 despite keeping a clean sheet and making 2 saves.

Like I said it's a fault in the game and until Nordeus explain it we will just have to live with it.

I am really getting sick of these problems, I have changed a whole midfield with low ratings and then my DMC gets low ratings so I change him and now my DC/DR is giving low ratings, I give up!
