Have lost three times all season, of which two were cup games and one was a league game using my reserves.
Last season I lost twice, of which one was the CL and the other in the Cup. I went a perfect 26 wins in the league, of which half of them was via my reserves.
My team was the strongest in the league by far last season and a considerable amount stronger in the league than others this season.
I have seen others lose to weaker teams (myself included), but not to the extent you're making it out to be.
