first off - you are only in league 2.
Don't bother wasting tokens on scouts and power training. You can easily win the league and stuff with older, good players that will waste 1-3 tokens per player. Hell, in league 2 you can win the league with mediocre , young players even
If you are in the lower leagues, it's better to just keep the tokens for the future for leagues where you will actually need scouts or alot of tokens to bid on players
