Hello, you can not have two under-21 and senior and youth teams, because they do not reach the days of friendly matches !!! Many less can be U21 and U23 and junior teams and senior, because not reach the days of friendly matches !! If not incentive youth teams, in my case I will cut half of them because I can never have them with physical state 9 !!
It is urgent, change the 4 days of friendly plus league's matches, to two days of friendly plus league !!!
