Under 21s

[musicman]

Hello. I have an u18s which has a full squad and plays competitively in a league. I also have an u21s which doesn’t play in a league. I have to arrange friendlies and choose what players will play in order to stay match fit or or build up fitness after an injury.

The u21 squad has about half a dozen players that were mo ed on from the u18s, plus whatever 1st team players I select in order to keep match fit. 

 It seems like a waste of resources and money to have an u21 team (especially one that isn’t even competitive) as I’m not a big club and I need to save money where I can. All my promising 18-20 years old years old  players either got loaned out or I gave them game time in my 1st team, if need be I arrange 1st team friendlies. 
Is it possible to scrap the u21s within the game, or is it a case of letting the u21 coaching staff go ? 
I am coming to the end of the season.
Thanks
