Just to explain little bit the strategy some during my period od last 18 seasons as NT coach.
We prefered to have training under control so almost all of our NT's have been training in czech clubs or our utopia clubs. As we are at BB small nation (now 134 active teams) we decided to train just some years of players. We have quite a lot of managers that are able to train well with trainer 7, youth trainer 6-7, gym 3. Quite a lot for train players from 5 or 6 drafts in o row, not enough to train best players from any draft. But the goal was to join at the same moment all the well train players by our best managers.
