what i`v done from start is buy medium rated young players but have watched market before bidding, this way you get 3/4 season with adding skill points and no using tokens so save them when needed to buy new player then sell simalar position so you won`t spend much more on new player, also with saving token from daily log-in i try and watch out for video, so far i`v been pretty succesful with promotion since start ( every season ) and had good cup runs, at the moment i`m level 8 and my ave team age is 20.8 so depending how season goes and still looking to improve team i should get another 4/5 seasons saving tokens,
