If there are 5* players on your TM, I'd get some of them for a low amout of Tokens at right this time of the season (like 10 days in). I got some 18yo 1point from 6* for 1T. Usually I aim for the expensive ones, because the noobs look for cheap ones, so I get the better trainers for a low amount of Tokens.

If you have problems to win, buy good scouts: 22-23y/o, 1-2points away from 7*, useful SA and preferable 2 positions (except GK and ST, in my opinion for ST a second position is not that important). But there are usually only 0-2 players of this sort per season :/
