Do you want to use young promising players and give them experience to make a better generation in the near future?
Of course yes!
For exemple, your player Kensuke Takagi, also has his place in the team, cause he is only 24 years old and wil lincrease his capacities for several more seasons. It's the same thing for players like Mitsuru Nagase, big potential and quite young.
At equal level and at equal shape game, I will always favor the youngest player.
I will contact the U21 coach, in order to know the strategy in place for young talents, or to set one up, if it does not exist, because training for the NT starts from the draft
