Don't forget about Confidence and Board Expectation. You simply can't expect a team to reach all the finals of every cup they entered. It's totally absurd to have "Minimum expectation" at that high level.
Also, new signings need more time than just 3 matches. Linking to that, DMC are usually poorly rated only because they do their job and not going into attack as much. Any new DMC singing would always rated "poor acquisition" or worse.
For youngsters that were signed, if they play in reserve team or U18, those should be rated as well. Fans do know and see U18 and reserve games. I'm forced not to sub them for some first team experience since I know they'd get rating of 6's which will eventually backfire me.
