The title winning team had amazing players that went onto clubs like Chelsea and Man City. Kante and Mahrez didn't become world class players when they took their Leicester shirts off and put their Man City/Chelsea shirts on.

Arsenal wanted to buy Vardy for big money (who in prime was world class) but he turned them down. Schemeical was fantastic in goal.

Leicester had the best team in England that season and proved it by winning the title. It was people's perception of Leicester that was wrong. 

Currently the answer to those questions, whether they choose to accept it or not, is:
'No, they are absolutely not acceptable or fair. They are beyond awful. Customers are not happy'

The core aim of any football management game is to produce a game engine to generate realistic, consistent and fair match results equally to all of its customers.

If that is currently not being achieved then an immediate examination should be made to ensure no bugs have crept into the game engine, and to check that any configuration connected to Continental cup competitions is set appropriately to provide a fair system that incentivises and rewards managers who field the strongest team.

That is a fair and reasonable expectation.

I don't mind if the developers silently fix the problem and don't announce it.  My only concern is that the issue gets fixed, that is the only update I want.
