Same here my goal keeper is a 5 star with 24 quality ...he gets a rating of 5 or six every game ... With full morale and condition ...opponents score filed goals from 25 / 30 yards with 3 star.... I have tried man marking so as not to give opponents time and space to take their shots ..still happens also my defenders are 3 and 4 stars with 19 to 22 quality they have ratings. Of 7 to 9 ...so it's not my team formation or orders that is mucking around with my "star" players form ....I will try renewing his contract and also play him out of position a defender or something to kick start a "glitch" probably ... Will let u guys know how it works ...and if anyone else has suggestions I'm open coz this guy is 0.2 points away from being a 5 star 25 quality 25 year old goal keeper and I don't want to sell him
