dont spend any token till the end of the season.. you should have more than 30.. then carefully buy young quality player in times there arent many users online to spend less token. and then just train them... while doing the same for the next season.. in 3-4 seasons you should have all your team with quality youngsters.. with the training this team will never have to buy new players for at least 4-5 seasons.. that means you should then have more than 100 tokens if you dont spend them.. then you refresh your team.. and so on...
