Help!? Minimum of 4 players trained between ages 15 & 21...

I did a cursory search of this site and could not find anything relating to my problem. Hope it is alright to post here considering it is somewhat support.

Brief backstory:
wanted to try a new challenge (no editing/cheating)so I chose a Semi-Pro club in Paris called Red Star 93. In my first season I amazingly won the "Coupe de France" which ended up qualifying me for next season's EURO Cup/Europa League.
The Problem:
Upon arriving to the EURO cup squad registration date it required me to submit a minimum of 4 players who have trained at the club for 3 years between the ages of 15 and 21. The club is so small that it does not have a single player that fits that criteria. Of course I have no chance in hell of winning the EURO cup with my current team but, I do not know how to forfeit the competition since the game will not let me continue without registering a squad that meets the competition's minimum criteria.

Thanks for any and all help.

Try to leave 4 spaces open. What I mean is instead of register 25 players register only 21 then the game should let you continue.

I only have 21 players in my entire squad. It still requires the 4, I even tried to include the under 19s with the auto select/manual attempts but still stuck.
Thanks for the suggestion though.

If this happens then you can try to go on a holiday for a couple of days until
the registration window closes..
