My child plays in the U13 challenge league for a club other than CESA. I don't see that these CESA '93 Premier girls are arrogant, nor do I think they should be playing down in their age group. If they did play in their own age group they wouldn't be as challenged as much as they are now. If it's arrogant for their coach to want them to play against the best teams and the best competition then so be it. But what benefit would it be for them to play in a league that they are going to dominate and not have the competition they are capable of playing against. Those girls have trained hard and earned their spot in the U14 challenge group. Give them the kudos they deserve.
