I actually didn't buy the 4* players to train them. They were purchased because they're immediately negotiation ready, so i'm just awaiting bids from lower levels managers so I can make a profit in tokens. An association teammate of mine already made 40-50 token profit this way on the 1st day alone. I probably won't be as lucky on my server, but still think i'll get a decent return (hope). Regardless, it's going to cost lower level managers less in tokens to negotiate with me, than it will to win a bidding war for the same player, so it's a buy low, sell high situation in my eyes.
