Kosovo only have one team with level 10+ youths, so if you are worry about the future of your team you could sell your players with a market value above 25000000 RSD like Ropero and concentrate on building those
Unless you have spotted a team with 10TC/10YF i won't recommended it, you still would have to deal with your rivals having better facilites than you and because you will have to build them they would have also more money for players.
